Hello,
As title says, i would like to switch to a different grade of oil.
I run a Toyota Diesel 2.2d4d over in the UK. Manual says i should run it on 5w/30 but dealer has performed 2 services 10 & 20k using 10w/40 shell oil.
Firstly if they are using the wrong grade, what potentially could happen? BTW: this is very common here in the UK, nearly all dealers are using 10w/40 i think as some European Toyota engines suffer from heavy oil consumption so dealers started using thicker oil, that and lower cost.
Now i'm thinking of changing the oil at 22k miles for 5w/30.
Firstly, would this be ok? Would the engine be run in and used to 10w/40 by this mileage. And is it also ok to swap oil so soon after a service?
Main reasons for swapping are: well, the manual say 5/30, also i'm worried about low temperature wear coming up to the winter. We get down to 5-10 degrees C but occasional drop to 0 and even had -8 for a week here last year. Also i think i might get better fuel consumption on 5w/30 and possibly smoother running. My only worry is how will the engine react to a thinner oil after all this time and will i get higher oil consumption.
Thank you
