"I hate to pop anyone's bubble but at a recient track day at Willow (NE of Los Angles) there were several new Corvette's running Red Line 5w-20 (street formula). I don't know any temps or pressures but there were no failed or smoking engines, and no little 'ole ladies driving, either, and it was a hot day. One said that he has been to three track days, changes the oil every 5k miles and every track day, 12k+ miles and still running well."

So, failed engines are common ? Oil changes every other track day, so maybe 200 mile oil changes ? If that's the case then no, it doesn't seem like normal driving with the typical long oil change intervals in Europe.

I believe he said it's every 5k miles, althoug it's quite unclear from the wording used. You can't get caught up with just viscosity. It's the total package. Their are some poor formulated thin oils and thick oils. Both can be good and ideal in certain situations.
 
Hi,
well Ted becoming personal simply won't help!
You said;
"I must say that Doug writes very coherently for an old retired (Mobil?) guy who's drinking that very fine, Australian Shiraz and Cabernet all the time..."

I have never worked for Mobil - only professionally contracted project tasks with my Company as for castrol - and the only thing I have ever received from Mobil for free was a hat and a shirt - I'll send them to you if you wish!

As for Turbo oil return temps you may find that these reach >300C with some - this is one reason to be circumspect in not considering Manufacturer Approvals. They no longer fail like earlier time but they do depend on a suitable lubricant!

Regards
Doug

As long as Ted doesn't take my Genoa Salami and Provolone, I might even let him cut in line.

Eggplant Parmesan on crusty Italian bread - lots of sauce.

Sadly not available south of the Mason-Dixon line.

Something that needs more exposure north of the Mason-Dixon line is 'Carolina style pulled pork', with the vinegar based sauce. We typically make 'pulled chicken' instead of pork, and just slow cook it until it pulls apart easily.
 
"I think that you guys may be obsessing over nothing. The valve train is the only adjustable engine component. A little extra wear in that compartment would be off little significance with respect to overall engine life as long as the valve clearance is kept within specs ."

Yeah, we're obsessive, so what :^)

I agree that it's typically not that big of deal, but the apparent differences between the oils are interesting.

I made a big batch of that for some native Texans. They enjoyed it immensely. It's now on the list of things to make for the local clan's Sunday get-togethers.
 
"Mobil 1 5w30 has been shipped with new LT-x and LSx Corvette engines for over 10 years now. I would think the internet would be choked with valvetrain failures stories on these engines if such were the case."

It doesn't matter what you put in if you don't use it. How would the Vettes with 5W30 hold up in Europe trying to keep up with the rest of the sporty cars ? Are Vettes that are exclusively club raced using 5W30, and if so what is the engine life ? Long engine with lots of sustained high speed driving is the criteria, which almost always excludes driving cars in the US.
 
I find the energy conserving, vinegar based sauces to be too thin.

I prefer a good 40 weight, tomato based sauce as it reduces molar wear - particularly if you grind your teeth at night...

Try the "Delvac 1, Barbeque Sauce" - it's to die for!

I only make it during the 3 coolest months of the year. I'm sure you heard how the Texas heat thins things out.
