enos 15W/30, hi force 15W/40, elf 15W/40 i had tried lot's semi-syn, but these was the oil that eliminate the VVti noise


Tried Mobil1 (5w-50), United semi syn (10w-30) & now United fully syn (10w-40). So I feel that the best response is from the 10w-30. The rest feels "heavier", probably due to its thicker viscosity.
So far, in my experience, in all the fully syn lubes I've used, the oil dipstick level will drop over time but not with semis. I wonder why ??
At first I thought it's due the the fully syn oil is thinner but even the 10w-40 also same wor.. but the semi 10w-30 needs no topping up. Strange...![]()
last time toyota engine oil usually from castrol
actually,pennzoil give UMW exclusive marketing and distribution rights so definitely UMW use all pennzoil lubricants since 1991.
Is is true that the fully synthetic lub is recommended to use with a good oil filter (e.g.KNN claimed that it can last up to 10k KM).
I've tried everything from fullysyn, semisyn and mineral. So far performance is better with fullsyn but 20V eats fullysyn oil too fast. Semisyn is also good, but mineral oil is the best if you wanna reduce engine oil consumption. So now using cheapo Elf 20W/50 mineral (RM35) and almost 1 month no noticeable oil consumption. Nevertheless, its quite irritating to check for engine oil for every 3-4 days in a week... perhaps special engine (more valves) requires special care taking I guess... LOL
