Has there been any scientific studies done by non-bias company's, away from the
oil company's, that show negitive or positive wear results when using engine additives ?
Aside from
zinc for solid flat tappet's, cam lube ect. for engine break in.
Many company's like Lucas, STP, slick 50, Prolong,
Amsoil ect......Is it worth the expense or is it just a ploy to get our money ?
Or, do you just believe in changing the
oil/filter often ?
With the sprint car, we change the 20/50 racing
oil after 2 races. We do use methanol so it's a cleaner burning fuel than pump gas, but after the season ending race, we tear down the motor for inspection and maintenance. It's amazing how damn clean all the engine parts are, running methanol.
When I broke a rocker shaft with my 428 FE after only 2,000 miles and removed the heads, the amount of carbon build up was shocking !
Since we buy methanol in 55 gallon drums, I almost put a alcohol carb. on my FE, and sometimes I wish I had but, it would restrict my driving to only local.
Anyway, back to additives.
Yes, we change the oil 20 times more than street driven vehicles ect.. but we've never seen any wear problems only using oil. I wonder if any engine builders like KC have torn down one test engine periodically, just to check for wear using a additive versus not ?
So, what's your thought's with any type,,..... of additives, worth it or not ?
