i would also do the sparkplugs
Spark plugs done in August.
I've been stocking up a lot of the Castrol Syntec LL-01 oil. They were $7.40/L so I stocked up on those.
Kbimmer - How much did it cost to you to do the tranmission oil?
Which Royal Purple do I use? Not sure what to use here.
For the rear differential fluid
Red Line 57904 (75W90) Synthetic Gear Oil - 1 Quart
Would that be ok?
