Hello friends,
i have an 81 GP/ Pontiac 265 engine, i keep seeing about zddp being good for these old engines.
Is this something i should be using? I see Valvoline VR1, Lucas Hotrod, and other classic car oils with more zddp.
Reading these it mentions not to use in cars with a cat (mines has it)
I know i have a crappy engine , but want to keep it running as long as possible.
Right now i'm running 20w50 conventional (have a rear main seal leak)
Any one else has had experience with this? First car i own being carbureted.
thanks!
