Hi all,
The aussie lube guides for my 351 Cleveland engine are confusing me a bit. Just looked on Penrite lube checker and they're recommending 20W-60 and even 25W-70 for this engine! I know that high zinc oils are recommended for these old tappet motors, but gee this heavy weight has me a little concerned, especially when the US sites seem to recommend 10w-30 and 15w-40. From looking on the BITOG forum, I can't see anyone running anything like this Penrite HPR30 20w-60 in their cleveland V8.
Can anyone give me some pointers about oil choice please?
regards,
Andrew
