Excellent site Brett! Thanks. Here are my questions:
1. I have a new Subaru with 400 miles on it now. This car has a 4 cyl. horizontally opposed engine with a turbo-charger. The manual recommends 5W-30 at temperatures 105 degrees and below, and 10W30 or 10W40 for temps. 0 degrees and up. I live in central Florida and drive 80% city. I plan to switch to Mobil 1 after the 1st oil change. Which weight might be best and should I switch to synthetic earlier?
2. It is also an AWD car and have read that synthetics are best for the differentials and transmission due to the higher stresses of AWD setup. What is your opinion on this?
