Hi,

Many thanks for all the replies. Looking back in my records, I was recommended by someone on here back in 2015 to try 5W30 rather than the recommended 10W40. This is because I bought a replacement engine which hadn't been looked after and rattles (possible hydraulic tappets) from the top. I'm not sure if 5W30 is thinner or thicker and what the thinking is.

Any advise appreciated.

Regards,

Terry.
