Racing oil

[theacr_viper]

I'm not sure it was talked about in the forums before but what is the down side of using racing oil in our track cars?
I have a prefix 9L with dry sump and it's mostly a track car!
I use AMSOIL Dominator 15w50. Runs great and it also has some Calcium in it which is a detergent. I need the extra anti wear additives that race oil provides, to get more life of the engine.

Do I need to switch back to a street oil from time to time? just to make sure it cleans the engine better? Or I could get away with engine flush products every time I do an oil change? Does anyone with a built motor run a street oil in their track car? and Why?

I have the Prefix 9 liter extreme motor. Dick Winkles says to just run Mobil One 15w50 in it. I track it often and the oil seems to work fine. I don't have an accusump or dry sump on it.

unfortunately we don't have mobil 1 15w50 in Dubai

TKO mentionned lately Diesel engine oil (better/more additives) but I don't know much about that. I might try it with my new racy engine

Dick Winkles specifically told me not to use Diesel oil. Too much detergent he said.

Even for a low-miles or rebuilt engine?

Dick told me Mobil One 0w-60 is good and that's what I use. TBH I think it doesn't make a difference which oil you use as long as you change it regularly.

Hey Alex, if you don't mind sharing what Mr Winkles think about jumping to a 60 weight oil! there is a lot of good 10w60 racing oil out there!

AMSOIL Dominator 15w50

Most probably a great choice for Dubai climate

I've been running it in my 440ci LS engine. Going to swap out for synthetic as I have about 1,500 miles on it since being built.

I chatted with Dick at his garage 6 weeks ago. He recommended Mobil 1 High mileage engine oil. Higher Zinc content.

I'll split 50/50 diesel oil and racing oil, problem solved (without too much detergent).
