I use Mobil 1 in my car since first oil change, and won't go back to normal engine oil!

But I will probably other brands if they are better.

 

Yes I am and have been for 25 years now. If I find a better product and a better company, I will sell that product.

Your convincing would have to include ASTM and SAE Tests. Those are the only true repeatable ways to test and prove a lubricant.

As long as it is Mobil 1 EP, you are using a good oil. Just make sure it is the EP


Doc

 

yea im using mobil 1 ep i have to say i felt a slight increase in performance when i made the switch i dont think i will ever go back to regular oil

 

Amsoil 0w-30 SSO

 

mobile 1 full syn 5w-20 with a mobile 1 oil filter M1-110, everytime i change oil i get a new filter, i change about ever 5k or 5months what ever is sooner just to make sure my car is in tip top shape!

 

So 2-3% gain in MPG. So that is a lot less money spent at the pump than you will spend on the oil. I run dyno is all my vehicles and they all last long. I have had two of my vehicles for years. Ran synthetic in one, then ran dyno in the other. Both the same pickups with almost same miles. I did an oil analysis after 50-60K and they both came back pretty much the same. Not much of a difference to spend 100's of more on synthetic than dyno. Case closed. At least for me.

 

Hundreds more? I know 1 Gal. & 1 Qt. of SSO (the best AMSOIL) + one of their filters is under $70. That's cheap IMO.

 

Please read to the end..

Sounds like this comes down to "All Synthetics Are Alike" which has been proven wrong over the years.. Also, you make it sound like 50-60K is a lot of miles.. I have 345,000 on my work van with less than 15 oil changes in the last 335,000 miles along with over a 5% gain in fuel mileage. No internal work has ever been performed, including injectors.

Let's switch gears to the auto trans... Original tranny went 125,000 on Petroleum fluid and it was smoked. Vehicle had a relatively easy life during that time.. Rebuilt the tranny, AMSOIL ATF 100% Synthetic used until 243,000 and then switched to AMSOIL ART Racing Automatic Trans Fluid (Type "F").. Still going strong and vehicle has been towing a heavy 18 foot trailer with no additional oil cooler.

Ford requires a 75W-140 Gear Lube for the differential. I switched to AMSOIL Severe Gear 75W-90 which also helped the fuel mileage and still running the same diff with no problems..

All Synthetics are not alike.. Most are Hydro-Cracked Products, some are PAO's, a couple are Esters and a few are PAO with Esters which has been found to be the best overall combination. We have taken part in Dyno Days at shops in the past with great results and HP gains.

The EVO comes from the Factory with a very respectable Synthetic oil installed. They don't use it because it is cheap, they use it to get better protection at a reasonable cost.

EXACTLY !! Also it is Cheap Insurance.. Best protection and the better fuel mileage starts to pay itself back right away...

With AMSOIL 100% Synthetic (excludes XL line) you can take your oil change from the OEM Recommended 3000 miles, safely to 5000 miles. 67% further which also is paying you back..

You own a Great Car, use a Great Oil and Filter in it.

Everyone can argue endlessly about synthetic vs dyno. I prefer dyno and i don't mind changing it more often, for a daily driver its not worth the extra, if you had a high end car then yes I would use synthetic. I change my oil every 5000kms and have no issue with doing this.

For those who like spending the extra money for their piece of mind then go ahead but my regular oil changes and regular oil will do just fine.

 

It goes beyond Extended Drains as all Synthetics are not capable of that.

I use to sell Turbo's a few years ago and one of the big issues was coked oil lines from using petroleum oil and not changing it fequently enough. If they wanted a warranty on the replacement turbo, we required the purchase of a new oil supply line.

With a True Synthetic being able to handle the heat, there is little worry about that. Also, a True Synthetic will flow better at cold temps to avoid oil starvation.

These may not always cause catostrophic failures immediately, but they will shorten the life of any turbo. Possibly a good reason why Mits uses synthetic from the factory..

GM uses Synthetic in the Vette for exactly that reason.... When you lock up about a dozen $25K engines because the temps are about freezing and the oil can't flow through tight tolerances, you learn quick.

The other benefits of a Synthetic such as AMSOIL, you can go to 5000 mile change intervals with no problem and beyond that with using Oil Analysis, which is a far cry from guessing if your oil is good.

Then we have the Facts of.. A smoother running engine, decreased oil temps, more HP, better fuel mileage and less internal wear.

For the trannies, smoother shifting, less wear..

Same for the TC and Diff...

All these benefits, in my opinion, far outweigh the few extra dollars for an oil change... The cost per mile is what you want to look at, not cost up front.. It pays dividends in the long run.

I always say, good results can be had by using a petroleum oil and good filter when changed often, Superior Results can be had by using a Premium Synthetic oil and a Premium Filter..

We can always compare mileage on vehicles, number of oil changes for that mileage and figure cost per mile.

At todays prices, it cost me $743.50 in oil and filters to drive over 328,000 miles.

That is without compensating for a minimum 5% increase in fuel mileage.

Looking at using Mobil 1 EP for my next oil change... But my friendly Canadian Tire near me only has the 5W30... I know Mits recommends 5W20... Is that anything I should be worried about? Could they refuse warranty based on not using the recommended weight?

 

No warranty concernse... 5W-20 is recommended for fuel efficiency. There is usually a little blurb in the manual that says something to the effect of " xW-xx oil may be used if a xW-xx oil is not available."

What you want to look at is the API Rating of which I believe your car call for an oil with an SM Rating.. That is what is important.. Because of the use of a roller cam in your engine, an SM or Higher rating is applicable but not less than what the OEM calls for..

Canadian Tire also is a large carrier of AMSOIL.... Look at the SSO 0W-30... That is what I run in my Lancer..

Doc

 

I checked for Amsoil and they only have the regular 5W30 and 10W30... No SSO...

I wonder if they can order me some...
