Hi.
I was told I should join here if I want to learn more about oil, so I decided I would. From the threads I have read already, I can see I'm at the right place.
I'm here because I need some help selecting oil for my car. I own a 1995 Honda Prelude SI VTEC that I'm going to be endurance racing on oval tracks. I'm not really sure what oil I should use in the car. I've been racing other types of cars for years(Ford escorts mostly) and have always used either Mobile 1 or Redline oil, but didn't really do much research when it came to viscosity. Those cars had high miles and I didn't really care if they held up or not. The prelude cost me much more than the escorts did, and the preludes are known to burn oil, and they have VTEC, which relies on oil) so I'd rather take my time and figure out which oil would be the best for the car. I'm not really sure which viscosity oil I should use. And I'm not sure if I should use a dedicated racing oil, or a street oil.
Here's some information that might help:
The factory service manual says to use 10w-30. (This sounds a bit thin for racing to me. But that's just my opinion.)
The engine is a honda H22A1, with 100,000 miles.
It's a race car, so it's going to be abused. (It will be run from 4500-7500 rpm every lap.)
The races are very long. (About 100-150 miles) There are no yellow flags, so the car will either be stopped and idling during red flags, or full throttle during green flags. There is always at least one break in the race to allow for fuel to be added and tires changed, and drivers to get some water and the car is shut off during these breaks.(they are anywhere from 10 minutes to 20 minutes per break.
The races are held year round so the temperature is different each race. Should I run the same viscosity all year round or should I change it when the temperature changes?
I want to use synthetic oil. I'm a fan of Redline oil, but will consider running other brands. (Except Royal Purple. You couldn't pay me to run that stuff.)
I usually change my oil after every other race. Sometimes every three races. (Is this ok? Or should I be changing it after every race?)
Another thing I'd like to know is if the car really needs an oil cooler. It comes with one from the factory, but I normally eliminate them because that's one more thing that can fail and cause the oil to drain out. I've never had any issue after eliminating them on my old cars, but I don't know if I should do it with this car.
What are your thoughts?
