oil- what brand, type, weight, change intervals
Im just curious as to what brand of oil everyone uses and what weight. Have you noticed any differences in the performance or protection.
I use Mobil 1 synthetic 10w-30. I have used it ever since i built the engine and have sworn by it since. i change it about every 3 seeks reguardless of miles but i useually clock on around 100-150 miles. I had the head off a few times and the top end looks like it was new. I didnt have many miles on it but the car has been run extremely hard and has several dozen quarter mile blasts.
