When I got the P2 at 121k miles I dropped the oil sump and cleaned the PVC system. Since then I've used nothing but Redline and Castrol GTX Magnatec for oil along with Purlator Plus and WIX for filters. Approaching 185k miles and the CAM seals haven't leaked yet.vtl wrote: ↑10 Jul 2023, 08:26Oh, mind you... This is a cheap junk oil for meThe car was running exclusively on Amsoil Signature and Red Line until the engine failed. After that I saw no reason of dumping $100 on an oil change for a car that barely sees the road. It may have 50k miles of life left in the rebuilt engine, but that's enough for good 15-25 years.
I switched to Pennzoil Platinum (no Ultra) on my big Toyotas. Will try PP in Volvo in 6 months.
The reason I decided on that Mobil is that I saw a picture of a V70XC's sump with almost no lacquer or deposits at all. The owner claimed he used it since new, every 5k miles.
Edit: Forgot to add that I also flush it with BG109 every three oil changes. Black oil drips during those flushes.
