Club 80-90 Forums

as above, first lot i put in was 10-40 the second lot was 5-40
What is the best one to use?

I was told to use 5w30 long life.

I use 10-40 Quantum Synta, local dealer had 25l drums on offer.

costco sells a american made branded 10/40 semi synthetic, or a 5/30 full synthetic in 20l drums for £40, think that it is chevron (the brand). has a good api rating too.
