06 forester x 5 MT
I have read tons of posts from fellow members who use Rotella T6 5W-40. I couldn't find any posts from those using Mobil 1 in the same weight. I admit, I am partial to Mobil 1. Why? Because I drove an 84 Firebird to 219k and it didn't use a drop between OCI. I sold that and bought an 88 S10 and drove it to 198k before it showed any signs of oil consumption. I used Mobil 1 5W-30 in both of them. I have an 06 Foz that I bought new and now have 109k on it. I have used Mobile 1 5w-30 since 1800 miles and now started using 5w-40 due to age and Florida summer heat. Having said all that, has anyone used Mobil 1 5W-40 and if so what was your experience? Thanks!
