My OM recommends 75w90 GL-4 or GL-5 for the manual transaxle. My dealer replaced the oil at 40k with Mobil 80w90. Car now has 46k.
Should I change the oil right away to the correct viscosity, or wait until 80k to change it and use the correct 75w90?
Available 75w90 here are the following. Which would you recommend?:
Pennzoil Synthetic 75w90 GL-5
Valvoline Synthetic 75w20 GL-5
THANKS!
