Noisy Engine--Thicker Oil

Postby Pierce » Thu Dec 07, 2017 11:51 am

My engine has done 80k and is noisy.Nothing specific just generally 'rattly'. Have talked privately to one of your experts on changing from 5w-30 to 10w-40 which he thought might be OK so that is what I did on a recent oil change. The garage owner (old school) was a little reluctant so got on to a special website he uses which gives refill volumes and oil grades. To his surprise not only is 10w-40 an option provided the temperature does not drop below -15C but also 20w-50 for hot countries where the temperature does not drop below +5C. Engine seems much quieter but can't really tell with current cold weather.

Try a new cam chain tensioner from TCB Performance (in Affiliates). This has been known to cure engine rattles.

I did the same on my old pre-fl mr2. Ran quieter on 10w40. Still got the good stuff mind, just 10w40.
Needless to say that only really applies to cold running. Once it's hot it's the same. Seemed like a good compromise
