Hi,

Please can you advise what would be the best oil to use on my 1970 454 big block, four bolt main with high performance pistons and cam.

This will be my first oil change since the full engine rebuild, since being rebuilt the engine has only done 300 miles.

Would a Non-synthetic 10w - 30 be suitable?

If I use Valvoline VR1 racing mineral oil what weight would be best?

Thanks in advance.

Hi Ross,

Thanks for your reply.

For my engine I think its currently got 10w - 30 from the rebuild, should I stick to this weight or move to 20w - 50?

Thanks again
