which oil is better for diesel??

[mbeige]

Tsikoteers, I'm due for change oil this month and want to try fully synthetic oil for my diesel ride. Unfortunately, I cannot find any syn oil with 15W-40 in laguna area. Only syn oil available is 5W-40(castrol,shell), and 20W-50(shell). which of the two i can use and is okay for an diesel engine.

Check the rating at the back of the bottle, it should be diesel-rated. You can tell if it has a C instead of S when checking the ratings. If it's S-rated only, it's not designed to handle diesel soot, but can be used temporarily as an emergency oil. Replenish with correct type as soon as possible.

For me I went from dino to semi-synthetic muna. Baka mabigla sasakyan ko. So far so good, I get better starts and feels a bit lighter with 5W-40 (here in the US I use Shell Rotella). Might use it for a while I think my car likes it.
