Sorry to disagree with everyone, but oil is oil when it comes to lubrication. I also use mobile 1, but have used everything from K-mart special to WolfsHead and I would dare say that there is one person out there that can prove or disprove that they have ever had an engine failure due to the type of oil used. Yes, Mobile 1 , and Amsoil, and Royal Purple have a slicker coating and probably less friction, but can using a reprocessed oil cause an engine failure, I don't think so. But, yes I do still use the good stuff.

Steet,

I think your comment my be a bit missleading. I'll agree with you that oil (for the most part) is oil when it comes to the petroleum blends. There, to my knowledge, was only two manufactures of oil on the east cost until last year or so. One of them was Sunoco. They no longer package and sell their own, or anyone elses oil, for that matter. So, that leaves one. The difference was additives that each company asked for.

Now, if you want to talk synthetic, it's a totally different ball game. Synthetic oil is NOT all the same. Those are the true facts.

Dave F, You are correct. What I said was misleading. I actually do not believe for one minute that all oil is created equal. I use only the best available for my engines. I use mobile 1 in my twin 4.3 SeaRay. However, I do stand behind my statement that in all my years of performance boating and high performance cars, I have never seen or heard of an engine failure due to the brand or quality of oil. Only no oil or no oil pressure. I still challenge anyone who can prove they had an engine failure due to the type or brand of oil. I had a roller lifter failure at 52 hours using Mobile 1, but was it due to the oil or just a bad lifter? I have read a lot of post on the bad lifter syndrome. My 2 cents.

I buy the cheapest oil they sell at my auto store, and all my vehicles are still running.

1998 Dodge Ram 1500 85,000 miles Tow vehicle
1969 Pontiac GTO 185,000 W.O.T all weekend
1955 chevy deluxe 135,000
1992 Jeep 100,000
2000 Sunsation 125 hours

All of them run fine and never had an oil related breakdown

Yes but if you guys ran a good syn and the oil went to 300 degrees due to some type of event it would not brake down like a cheaper oil and protect the rest of your parts where the cheap stuff you'd loose a lot more !!

Also on oil filures most of us don't keep our toys long enough to see a catastropic failure due to oil ,the man thing is the added wear protection and insurance . And that can be proved by oil testing and has been for years ,there are alot of advantages to good oil and keeping it changed in a good motor that you want to keep and not sludge up //

I have 50 hours on my engines thus far using a straight 40wt mineral based (non-synthetic) oil. I have allowed this for break in time. This spring I will be using a synthetic oil (most likey Amsoil).

Steet,

I can't think of any oil related failure due to brand name either. The closest I can come to that is I knew someone that had a failure due to the wrong weight oil.

I used to use Sears oil in my car. Sunoco made it.
