I want to hear from people other than RLI's proxies.
Any issues with veg-oil based bio lubes? Seal compatibility, yada yada...
1996 Audi A4 V6 12v engine with 160k miles on the clock
(low tension rings, valve stem seals leaky, no fuel dilution issues despite running on the rich side, fair amount of insolubles, but not critical, wear good and TBN okay with 8k mi OCI, oil consumption still within specs but nothing to write home about, engine does not produce any noticeable blue smoke blue)
Oils that have worked well in the past:
- Castrol 5W-50
- Chevron DELO 400 15W-40
Oil that worked well, but with increased oil consumption:
- M1 5W-40 T&SUV
- Pennzoil Platinum 5W-40
- Red Line 5W-30
Oil that I didn't like due to rattling noises and insane oil consumption (up to almost double of the above oils!):
-M1 0W-40
Currently using Castrol 5W-50. Consumption is about 0.6 qts per 1k miles with mostly city driving. High vacuum driving conditions definitely contribute considerably to oil consumption in this engine.
A penny for your thoughts!
