Mobil 1

The Best Since Day 1 – I started using Mobile 1 as soon as it first came out in the U.S. I used it in a whole series of Volkswagen Beetles I owned - 57,60,65,67 and 68, all driven hard long miles. Air-cooled not so easy on an engine but these all survived without a hitch and no oil burning - just time to sell them with the other car components worn out. On to a 1967… Read more

Ford F-100, 240 C.I. long stroke with NP truck transmission - drove it like a diesel through mud, rocks and amazing hill climbs on Mobile 1 with no oil burning and perfect performance. When living in Canada I drove a 2014 Ford Explorer for 290,000 miles, sometimes many days at -40 degrees without a hitch on Mobile 1, even without plugging in the engine heater. Mobile 1 - always been the best!

Information on Mobil 1 from a former ExxonMobil staff member – I'm bias because I know what went into the development of Mobil synthetic lubricants and over my 35 years working for the company, I got to see what goes on behind the scene to make sure this brand is genuinely No 1. There isn't a gasoline engine on the market in any country that won't benefit from Mobil 1 and that's only one reason why top… Read more

brands like Porsche and Bentley restrict their service requirements to Mobil 1.

Without getting bogged down in what oil should go into a particular car, I've got a story to tell readers, but before I get into that, remember this - Viscosity is not an indication of quality. It indicates the temperature range that the oil is intended for. In saying this, most car engines built after (say) 2000 were designed for fuel efficiency, hence the reason manufacturers specify low viscosity oils EG: 0W-40 in Porsche while most other manufacturers want 5W-30 used throughout Australia. That said, anyone living at Broken Hill should use 5W-50 viscosity in any gasoline engine simply because of extreme summer temperatures.

With regards to how long an oil should be left in an engine, consider this: Mobil 1 is designed for longer service intervals and will manage high temperature extremely well. Today, it is perfectly safe and sensible to change engine oil once each year, regardless of mileage traveled. If in doubt follow the recommendations of the vehicle manufacturer in the owner's handbook.

Back to the story I mentioned previously.

Most readers will know that Peter Brock was an avid Mobil 1 advocate and he had good reason for that. During the early 1990's, Brock operated the "Mobil 1 Racing Team" and Larry Perkins was the team No 2 driver. Larry is a qualified automotive technician and he knew auto mechanics inside out. He wanted to use Castrol products in the race cars.

To decide which oil would be best, Brock decided to run a test on a Dynamometer to find out which brand gave the highest power output at the back wheels. This was a tedious, time-consuming process conducted at team HQ in Melbourne. The end result was Mobil 1 15W-50 (used at the time) in the engine and Mobil SHC synthetic gear oil in differential and gearbox produced the highest brake horse power at the back wheels on the test car.

Needless to say, Larry was convinced by the results and Mobil products were used. Now, I can say this today - there were a number of other race teams visiting our team track-side with other branded containers that were filled with Mobil oils for their teams to install in their cars.

Summed up, there isn't a better engine lubricant on the market. Some manufacturers don't tell the complete truth about the contents of their products in an attempt to make their oil seem unique. Synthetic is used in instances where it isn't entirely true, so if you read comments like this, you will be aware of what you are NOT buying. "This oil has an enhanced additive packaged that provides Synthetic like performance". NOTE: The additive package has zip to do with the base oil in the product which makes up around 60% of what is in the container. Therefore, the quality and characteristics of the base oil is critical to performance.

FOOTNOTE: My comments apply to all viscosity options of Mobil 1.

Best engine oil that I have come across with – Been used manufacturer recommend engine oil; Castrol Edge professional 5W-30 (VW 504/507) Fuchs GT1 Pro C3 5W-30 (VW 504/507) Penrite enviro+ 5W-30 (VW 504/507) Shell Ultra ECT C2/C3 0W-30 (VW 504/507). I usually service my vehicle based on every 5-6000 (Max) kms or 4 months, due to tappet noise from the engine at cold start, and the color of the… Read more

oil. Recently I switched to Mobil 1 ESP 5W-30 (VW 504/507) driven 3800+kms, the color of the engine oil on the dipstick still remained transparent to light brown, Cold start tappet noise hasn't appear yet, since last oil changed with Mobil ESP 5W-30. I am really getting the benefit from the product. 2012 VW T5.1, 2.0TTDI, with 74,000Kms

The good oil – I use this in my 2000 Mercedes sprinter. Had tto take the head of at 375000. Could still see the hone marks in the bore. My mechanic said keep using it. Now over 500000 kms still going strong. I try buy when on sale. Show details

When you are on a good thing stick to it - er sorry wrong brand :-) – I have been using Mobil oil for 33 years, originally due to price when I could buy a 1lt tin of 20W50? in Franklins (that was a supermarket like Woolies) when I got my first car. For the next 23 years I was able to buy the same or next era version at supermarkets etc at a good price. My last car, 1979 2lt sigma which I owned from new had the… Read more

engine partially rebuilt (by me) at around 200k, Mitsubishi's back then and prior were notorious for rings wearing and burning oil (unlike Datsuns I had owned previously). I put a new set of rings in, pistons were borderline which I later regretted for not replacing due to ring groove wear, and new bearing as they were cheap. When I queried the plastic wrapped new bearing size compared to what I had removed (and had on me) the service dept of the dealership said they had seen more wear on bearings that had done 20k compared to my 200k. I ended up selling that car at 350K many years later, still using Mobil oil, and to the first person who looked at it - and without driving it. Compression was down due to not replacing pistons which I realised after the rebuilt motor was run in but that was a borderline decision which in hindsight was wrong based on advise.

When I got my next car, 1998 Toyota Camry V6 which I bought 2 years old with 44k on it I realised this engine was a was a precision built instrument I would never be able to rebuild to anywhere near the same tolerances. Appreciating this beautiful motor I decided to use the best Mobil oil to increase its longevity. (I don't replace cars frequently - and with current car now almost 20 years old that is the general frequency). I have used the fully synthetic oil since I bought the car in 2000, now has 265k on the clock and uses no oil at all. It has a very slight knock which was there when I bought it (was an undercover detectives car which may have been given a caning before run in properly), but that knock has not got worse in 220k.)

I had been buying the oil at Supercheap when on special before they stopped selling it, then Repco when they had the big NRMA membership discounts every few months, but even then the price was expensive. I generally buy good value products, and Mobil 1 was no longer good value, but because I had been using it so long and my Camry was lasting so well I ignored the price. Currently 265k no oil burn at all. The oil does get a bit dirty by the time I change but when I replaced the rocker cover gaskets a few years back the rockers and cam were so clean!!

Unfortunately my local Repco no longer stocks the oil so cant buy on 30% discount etc which makes it a very expensive oil compared to the opposition. There may be equally as good oils out there such as Penrite, Shell or Nulon, but when you are on good thing stick to it - if you can.

I have used Nulon additive in a gearbox to quieten down 5th gear (79 Sigma) so have some appreciation for the brand but have no real experience in alternative oils to the Mobil 1 5W-50, Nulon, Shell, Penrite or whatever alternatives. Would be interested in peoples opinions now that Mobil 1 is no longer available at good discounts and other brands have better retail awareness/price.

Excellent oil – This oil is excellent in the Buick 3800 V6, no complaints whatsoever...ok maybe oxidation is a little high. Shear stability is very good though and so is the additive package. I have been putting it in this engine for a number of years now. I think the formula has changed once in the time I used but it still seems to be more or less just as good. Show details

"Simply the best" – I have now been using Mobil 1 for 20 years and never had any problems. I first used it in a XE Falcon with a rebuilt motor, after 330,000 km the motor was still ran like new and consumed little oil, the car was written off but the mechanic I sold the engine to pulled it down, found it still clean inside and with little wear. The next car is a… Read more

2003 Subaru Forester, started using Mobil 1 from the first oil change, it has now gone 480,000 km and still good, burns about 1 litre oil 1000 km, no engine noises or rattles. Third vehicle is a 2007 SY Ford Territory with 320,000 km on the clock, engine still runs like new, and has never been opened, it uses about 1 litre of Mobil 1 between 15,000 km services. The exhaust system and catalytic converter is still the original, only one oxygen sensor has been replaced. The spark plugs only need changing every 150,000 km. I am using Mobil 1 on my FGX which has done only 40,000 km, barely run in, no noticeable oil consumption at all between changes.

Another good reason for using Mobil 1 is that where I live the temperature can fall to as low as -8 in winter, Mobil 1 synthetic oils do not thicken like conventional oils which allows the engine to start faster, the oil starts circulating more quickly, and warms up more quickly. I would recommend it to anybody.

Excellent, stopped noisy camshaft tappets – Found this oil on heavy discount at Supercheap. Said they were not restocking Mobil because it was too expensive and didn't move. My dads Honda CR-V had a noisy top end. After flush, filter and new Mobil 1 the noise had gone. Not sure if I would pay the premium price next time around, but the CR-V sure does run well now.  Show details

BRILLIANT!! – This oil is very good for my engine, no dramas with it, this is the same exact oil that my local ford dealership uses in services, this oil is well recommended for anyone wanting some awesome performance, Mobil 1 is the best and even better than Castrol oils all the way  Show details

Only Oil I use – Lost my 4x4 in a river, pulled it out and drained cylinders via spark plug removal. Drove for 10km listening to a loud equal coming from the engine, pulled the dipstick and the oil had emulsified to a yellow custard but the engine did not seize and went on to do another 160,000 km fault free. Try doing that with a lesser oil.  Show details

Mobil1 5W30 Dexos1 – Good quality synthetic oil. Car ran very smooth on it. Good cold start flow, much better than Castrol Edge 5W30 but I guess that because of it's PAO base stocks. Edge 5W30 isn't a proper synthetic. Have had the chance to try Motul 300V 5W30. Sure it's twice the price but it's twice as good as M1. Improved oil pressure & VVTi performance. smooth, proper synthetic(although it doesn't have as much PAO in it as older brews has) RRP is a bit step

Mobil 1 starts it life as the highest quality oil you can get before it’s refined into Mobil 1 – Being an Engine builder I get asked this question all the time! Let me just start with if you use a reputable brand and the correct viscosity oil that has been internationally tested in a normal unmodified car – you will not have a problem. Also don’t believe the [censored word removed] about how one oil (Same Viscosity) can produce more… Read more ·  5

power than another oil – the benefits are unmeasurable on a Dyno!

Do you want the best oil?

Ok – well all the engines I have built then tore down after racing for a rebuild I can honestly say Mobil 1 has been the best without a shadow of a doubt.

The engines remain clean after furious driving conditions – which means the oil does not breakdown or contain impurities and also has the right level of detergents.

Mobil 1 starts its refining from very very high quality oil – you pay for what you get.

That’s right Mobil 1 starts its life as a PAO oil – the highest rating you can get. So it’s already the best before it starts (one reason why it’s so expensive).

Some other Synthetic oils live on the “edge” and actually start life as a grade 3 or tier 3 oil then its Hydrocracked to try to make it better. Don’t get me wrong these are still very good oils but in reality Hydrocracked oil should not be as expensive as Mobil 1 by a long shot!!!!!

Another reason you might want to consider Mobil 1 over the others is that Mobil is an oil company and therefore has access to high quality oil reserves first – other smaller engine oil sellers have to purchase oil off the exchange and have to dose their oils up with additives to make them better. Feel free to have a look and you will find most small engine oil sellers started life as oil additive businesses.

Another thing I like about the Mobil 1 product is as an engine builder I can choose any viscosity I require. The others usually cannot as they have dosed their product up with so many different additives that some of their product cannot be used in some engines.

So to sum up – Mobil 1 is the best engine oil just not from the protection it provides but the fact it actually starts life as the best (PAO) oil available. It starts life as the best oil you can by before it is refined up to Mobil 1 Because other companies are Hydrocracking grd 3 oils and charging the same price as Mobil 1 this may force Mobil to do the same and downgrade their product over time!

Mobil 1, 5-50W Full Synthetic Engine Oil – Bought 25 litres of this oil at Supercheapauto when it had the 20% sale. Very good oil for my Honda 2004 Accord Euro Luxury and my Nissan Maxima 3.5L V6. Both vehicle responded very well to this oil. Quiet start up, smooth engine response, stronger engine performance at higher speed, quieter tappets. Again, the oil cleans the crankcase very well.… Read more ·  1

Engine crankcase very shiny in both vehicles. Lexus LFA uses this oil as factory fill, along with many other prestige and high performance vehicles made in Germany and Japan. Cheaper than Mobil 1, 0-40w. Provides higher engine protection, at 50W!!! Especially under the hot, harsh Aussie sun. Smooth engine response. Higher engine temperature protection. Factory Fill for Lexus LFA and many other high performance German and Japanese vehicles. Tappets are quieter.

Awesome oil for the car. Cannot fault it in anyway except it is too expensive! At $95 for 5 Litres! – Tried it twice in my vehicle, has excellent cleaning properties. As well as making the car go a lot faster, smoother, quieter and more responsive than ever before. It cleaned out my engine crankcase really well, very shiny inside, and fuel economy improved as well. Zero oil consumption after 10,000kms per oil change. Too bad I won't be buying this… Read more ·  3

oil anymore as it has gone beyond my budget. At $95 for a 5 Litre bottle at Supercheapauto, I will be switching to Castrol Edge Sport 0-40W at $85 for 5 Litre and then once I have tried Castrol Edge Sport for a year, I will try Shell Helix Ultra 5-40W at $65 for 5 Litre. Other than the steep price, it is an excellent oil if you have money to burn. You will definately notice a massive improvement in your vehicle engine performance once you switch from Mineral based oil to Mobil 1, 0-40W Full Synthetic Oil. If I have money to burn, I will keep buying Mobil 1, 0-40W oil for my vehicles. Cleans engine extremely well. Smooth engine running, quick response, fuel savings, quieter engine during startup, idle and under hard acceleration. The price...$95 for 5 Litre at Supercheapauto!!
