Yes absolutely, SAE-rated synthetic and conventional lubricants are compatible with each other. Even different viscosities. Like if you mixed 70W-90 with 80W-120, you'd essentially end up with a 75W-105.

adkjoe Well I ended up just putting In a new steering stabilizer tonight, not enough daylight to do the diff. Anyone else see a problem with mixing those two valvolines?

Otto Man mix 'em! You can mix engine oils, and they make blended oils, so why not gear oils.

adkjoe Any reason these two can't be mixed valvoline durablend synthetic blend and regular valvoline both 80w-90. Am about to refill the front diff would like to use these up. Both meet same specs etc...
