In a Toyota 2.7 (2tr-fe) that sees mostly 75% plus highway driving is there any reason to believe super tech synthetic can't go the 10k oci as recommended by the mfgr?
Current UOAs are with M1 0w40 and I've had a TBN over 4.5 each time after a 10k oci
Same question for a Toyota 4.0.
Reason Im asking is I'm considering switching to D1G2 oils and simply buying off price as its proving to be a very strong spec...and I like the concern for timing chains. The zinc in M1 0w40 concerns me a touch.
Both would be getting 5w30 as per the mfgr.
