- Shell Rotella T5 0W-40 $8.25/L(4L $33) (maybe cheaper at Traction, didn't check)
- Shell Rotella T5 0W-30 $6.00/L (4L $24)
- Mobil 1 Turbo Diesel Truck 5W-40 $8.40/L (5L $42)
- Castrol Syntec 0W-30 $9/L
- Mobil 1 0W-40 $10/L
I think the other grades of Rotella will probably be cheap there too. I'm really impressed with this oil and it's pricing. I will probably be going with that, either in 0W-30 or 0W-40 T5 for winter, and probably 5W-40 T6 for summer.
I'll report back here sometime in the future to fill everyone in on any fuel mileage changes and/or running problems/concerns while I'm trying this stuff out.
Also I recently found that my city, little as it is, has one of the Shell "Express" UOA test centers and I might be able to get my oil tested locally too. If that's the case I'll try to get some of this stuff tested and report back on that as well.
Thanks everyone for the suggestions and advice.
I would just run T5 0W30 year round. You are not going to have to worry about the issues that Volvo was concerned about with a Conventional 5W30. That 0W30 is designed to stand up to the gear train on the front of a heavy diesel without excessive shearing. You will get some initially then it should stabilize. Besides most likely that oil is on the heavy end for a 30 weight compared to most car oils.
I would test the oil in 5,000 km steps starting at 10,000 km. I suspect it will go 20,000 km but it might not go as far as I suspect or might surprise me and go 25,000 km.
Diesel engines have lower turbocharger temperatures when compared to gas turbochargers.
This is why no matter what the manual says, I find that conventional oils always leave varnish in a turbo.
M1 0w40 looks best to me for this car.
