We just bought a 2005 XC70 with 94K miles on it. The car is in great shape and the drive-line runs strong. I'd like to keep it that way till 200K+.
This car has the B5254T2, A 2.5L 5 cylinder VVT with low pressure water cooled turbo. By turbo standards, I wouldn't expect this engine to be hard on oil, and Volvo's scheduled maintenance seems to agree with this... If I understand correctly, Volvo specifies conventional 5w30 Castrol at 7500 mile OCI's or Castrol SLX LongLife at 18,000 miles OCI's for these engines. This vehicle was dealer serviced according to volvo schedule at roughly 7500 mile intervals so I assume they were using conventional in it. I've seen them specify 10W30 for higher temps and 5w40 for "all" temp on this engine but not specifically for this car (funny how that works).
I'm leaning towards using Rotella T6 or GC 0W30 in this thing after an ARX cycle on mobil 5000. (The ARX cycle should wrap up right around 100K, how convenient!).
I'm tempted to try a "1 year" OCI on synthetic and send in for UOA, see how it went. For us, 1 year should be in the neighborhood of 8,000-10,000 miles. If I could develop a once yearly service interval for the vehicle that would be great.
What do you guys think? Any other oils I should be looking at? Mobil 0W40 maybe? I'm leaning towards the T6 as I suspect it is a better candidate for up-to 10K intervals.
Thanks,
Eric
