The bottom line is you can use synthetic oil in any car or truck as long as it meets the API requirements period. I have been using Amsoil since 1996 and yes I go the entire 25,000 miles between changes. Most people would never consider doing this, but I have 14 years experience plus over 800,000 miles driven between 4 vehicles and I haven’t had one problem nor has any Car Dealer questioned my use of Amsoil for such long drain intervals.

I had the opportunity to travel to Europe in 2007 and did a little research while I was there. First of all there wasn’t one quick lube in the entire country of Italy. Why? because in Europe they have been changing their oil once a year for over 25 years. Most Europeans take their vehicle back to the Dealer once a year for a complete maintenance check list and that’s about it. All fluids are changed if necessary and out the door they go. They don’t talk about voiding warranties over there because they use oil that last and doesn’t break down unlike the cheap crap being fed the American public. Cars in Europe last twice as long as they do here in America and you can relate that to the use of high quality synthetics.

Most people error on the side of safety and choose shorter drain intervals, but you’re really wasting a lot of money. Don’t let the Dealer scare you into using cheap oil because all that will do is shorten the life of your vehicle, which is probably their ultimate goal.
