20w-50? or 10w-30?
ok guys this is the first time I do an oil change after the engine mods (pulleys, headers, heavy cam) im about 613rwhp/620tq. Before the mods, I had the free dealership oil changes. It has come down to the following oils and I am seriously stuck. I dont know which route to take on this. I need help! lol
I know I should buy 8 quarts. and I am going with the royal purple filter. Unless yall recommend I go with something else? I remember the tuner told me to go with a heavy oil 20w-50. That is why I chose the VR1, but Ive heard recommendations on the Amsoil Dominator, but that one doesnt come in 20w-50. Valvoline 822347 VR1 SAE 20W-50 Racing Motor Oil AMSOIL DOMINATORŪ 10W-30 Racing Oil What do you all recommend? Money isnt an issue when it comes to my baby lol Thanks guys

Mobil 1, can't go wrong. I would stay away from anything Royal Purple. I used their gear oil in my '67 and when I changed the diff cover, the oil just pooled in the bottom. I had a '71 race car at the time as well, used Red Line in that one, did a new cover at the same time, I had to wipe the oil off with a rag, it hung on to the gears that well. Can't speak as to their filters...

These are tight tolerance engines. Putting thick oil in them is not doing yourself any favors. |
