Otherwise my thought was to run Motul Gear 300 LS. It worked quite well in my Audis and is also a stout formula.
I see no advantages of using Renewable Lube over the Motul Gear.
Cheaper: $12 vs $25
Easier to get: Amazon Prime vs online retailers with S/H charges
More impressive VI: 187 vs 161
Is there anything about RLI that causes you hesitation for heavy-duty use?
