I have a 1994 Honda Accord EX with aprox. 92K on it. I use Mobil 1 5W30 SuperSyn and change the oil as specified for severe service in the owners manual (every 3,750 miles). I was thinking about switching to Amsoil XL-7500. Which oil is better? Should I just stick to Mobil 1? Am I changing the oil way too much with Mobil 1? Can Mobil 1 last longer than this? I called the Mobil 1 tech line and they stated to follow your owners manual. Thanks for the advice as I am obviously a novice here.
