1. stunston Says: Before I started using (and now selling) AMSOIL, I would either call or email the motor oil companies of oils I wanted to use and ask them your specific question. Emails were awesome because I had something in writing. You'd be surprised at the responses.

Some would say 10K in normal driving conditions, others would say "follow your owner's manual". You also must consider the oil filter. Usually, not always, the more expensive the oil filter the longer it can last. The one you're using, M1 Extended oil filter kicks A, can't go wrong using that one.

I've included Pennzoil's contact info as one of my sources below. Also, check out my website (www.familyfleetoil.com) and if you're interested in AMSOIL, let me know... I can get you wholesale prices if you're interested. Thanks.

2. Roberto Ruiz AMSOIL Dealer Says: 3,000 miles, why ? does your engine stop when you are at a red light, no it keeps running, so in actuality you now really have 5,000 miles running time.

3. Tony Marciano Says: 10,000 > 15,000 miles or change every year

4. Henry William Says: Depends on the conditions in which you drive, and the condition of the engine.
