Here we go... ask a simple question and you get a "here's how you should run your race program speech." please spare me...quote:

In a toy (yes I said toy!) like a race car/bike, Ferrari etc. you are already beyond the cost of something cheap like oil or filters. If you used 5 quarts of $20qt oil that is only $100 per change and you could likely afford a few changes a season if you can afford a drag car. Not trying to be insulting but what is your car/motor worth to you? Is it being rebuilt every season anyways? and if it is why not use the best oil for it anyways? The cost of oil especially in a application like this is the lowest cost you will likely encounter.
Hey Mark, thanks for the link. The csT of the 20W-50, I posted the VOA and UOA on, are most likely different than this late model version. The oil I had was made and purchased over two years ago and represented the last of my stock. Sense that time Kendall was sold a few times and the general feeling is it's not the same Dino oil. I know many racers and everyone jumped ship. Many have large stocks they horded when it became clear what was going on. The new 20W-50 looks, smells and feels way different. Would be interesting to see a VOA from Blackstone on the Kendall. The one you just provided the spec sheet on. I'm surprised the part number is the same. This specification sheet does not show all those critical additives except zinc. Figured they would have been a tad more honest and use a different part number. O well buyer beware. The SUS @ 210 from the VOA test was 94.4. If I'm reading my "grade system" chart right, that would be around csT@100=18.5 and csT@40=220. late model spec sheet has 19 and 174 . I guess than means it is thinner at lower temperatures??? so much for the 20W-50. Now the 70 is way off from my needs csT@40=380 and csT@100=37. I never get my oil hotter than 210F and never colder than 140F. I suspect if I ran the 70, the filter bypass would get one heck of a work outquote:

OK no problem. Racing is like running a business. Anything you can do to lower the O&M expense is a good thing. It's never been proven that running a $7/qt oil will make a drag race engine show any less ware that results in a cost savings when rebuilding. The big Benni of a Base 4 and even a ester base oil is for high temperature operation. Drag racing, like I do, only results in oil temperates of 210F max. There are some other benefits of a better oil, but again I have never heard or seen how that results in less/better operating cost or reliability. We never try for extended oil change cycles so scratch that as well. With 1000+hp engine, 25 1/4 mile runs is a great deal of use. Speaking of racing I have one to go to now...quote:

I apologize if you think I was telling you what to do quick_16. By the way I know nothing about racing so you are miles ahead of me as far as this goes. I was just inquiring as to why one would look for a cheap maintenance product for something expensive instead of a good or better product. It seemed kinda like Boeing trying canola oil in the 747 because it was a better deal than Mobil Jet Oil II. Again if I have stepped on toes I am sorry. Like you said it "has the potential to catch some heat"
I have spent recently spent a fair about of money to find an answer. Not all, but most reputable oil manufactures that claim to have a race oil in fact do have a way different additive package. Many of the additives for long use are oppose the ones needed for high HP racing. Zinc is a big one needed for racing same with Moly. I wish you where right on this, but have been been converted and just want to share my understanding. The key for me on all this can bee seen as an optimization problem. What is the lowest cost oil that provides the best service for my operation. When I have that answer, I'll post it here. For now Vavoline VR-1 20W-50 will have to do. Tip the cards >>>> So far I'm leaning toward Schaeffers oil. There straight weight micron moly oil seems to be looking very good... PS I run Nitrous Oxide on a timer just at quick-16 events... (I also bracket race on HP) that works out to be (actual time racing) about 10% of the time under full power on NO.quote:
