A friend of mine that is an M.E. for Porsche (is that like a yugo?) says he knows of quite a few Euro car owners are swapping out the syn oil out of their brand new cars and running mineral oil for an easy 1000 miles or so to get things to seat much quicker, and eliminate the drag on of oil consumption for several 1000's of miles. Anybody else hear of this? I know about regular motor rebuilds and such, and our warranty needs...anybody have a thought on this?

My M5 has break-in oil in it from the factory, it is marked all over the engine, I do not know about mineral oil though.

Check out this thread http://www.z06vette.com/ubb/Forum2/HTML/000002-2.html
Read the post by TAL.

Last night on American Muscle Car a Castrol rep suggested mineral oil for break-in as well.

My M3 came with break-in oil and my dealer was adamant about getting the car back at 1000 miles to get the oil out. I guess that's why.

Are you saying that all those engineers at GM are wrong?

I'm certainly not saying that. I'm sure they meant to design an engine that consumes oil at an incredible rate. I have to admit as a substantial stockholder in a major oil company (or is it the other way around

), I love it. But as someone with two Zs on their way, I'm a bit curious that's all.

I've done a bit more reading and thought on the idea and now have put mineral oil in my new Z06 at 100 mi, and plan to take it out at 1000 miles. I think in an ideal world GM would do that too, but given the average buyer(even of corvettes) probably do not bother to change the oil the first time until told by the DIC or many 1000's of miles, they don't want to risk having a break-in type mineral oil or additive in too long. So they go with the syn oil as a 1st fill regardless. I'm not going to run hard until I put the syn oil in, then probably red line and change ALL the fluids at about 1000 miles.

So the next question is this: if one follows the GM recommendation of 500 mi. break-in with Mobile 1, is this long enough, or should one stay off the throttle longer (assuming of course they were so inclined) ?

I have always followed the manufacturer's recommendation in the owners manual, but am interested in the mineral oil theory.

Any Engineers out there?

Mr. 427,
I guess your post is mixed up in mine, I didn't post all that. Ask most engine builders, custom and exotic, and they breakin a motor for a few miles or a bit of time on the dyno with a single grade mineral oil.
Found this article http://www.vtr.org/maintain/lubricants-redline.html

Interesting article in Auto World Weekly about synthetics. The mentioned many of the early synthetics did not swell the seals in the engine like mineral oils did and all the modern synthetics do.

When I used to build engines for my 64 Corvette, I always used a straight weight mineral based oil for that 20 minute break in because it was the cheapest. After the break in, off we went to the track and ran the crap out of it. The engine never burned oil unless I would spin a bearing or something dumb like that. Usually I would wear out the rear main oil seal and have to rebuild.

On the Z06 I broke it in rather easily for the first 500 miles, babied the trans and ran the car hard for the next two hundred miles then 41 passes at the drags and 36 runs at the autocross course (12 runs I hit the rev limiter in 3rd) and after 1200 miles it has not burned any oil. probably dumb luck!!

Mr David P....the article you suggested from red line indicates they would recommend a single viscosity oil for breakin, no mention of mineral oil. A single viscosity oil in not necessarily a mineral oil. Most oils can be purchased in single viscosity. I just spent half a day with the best engine builder in this country while I was at the Daytona 500. Quote "it is a myth that you should not use a synthetic oil at breakin." he did a dyno pull while I was there on a stock cube but tweaked LS1, per his specs that pulled 489 BHP. It was filled with synthetic Royal Purple oil at breakin.

I'm thinking myself of using royal purple down the road, I've heard it makes the most power. Anyone out there using it, and why versus redline or m1? I wonder why even those builders that use syn oil to break in use a single wt?
