Only synthetic (Mobil-1/ 5w30) oil in my 4Runner....and I still change it every 3,000 miles. Most of the time, it still looks halfway clean when I drain it.
:awais:
A waste of money? Well, probably not; as I can buy 5 quarts of it in a jug for about $22 on sale at Wally World and get my filters from the stealership for five bucks. Total cost = 15 or 20 minutes of time and less than thirty bucks cash.
That is still less than a stealer or one of those "quickie lube" place might charge, and I know it is done right and that my engine gets the extra protection of synthetic (whether it needs it or not). Best of all, I get the peace of mind knowing that my baby gets the best I can give her.
I leased my 4Runner (less than a year remaining on it - Boo Hoo!) for 3 years and 36k (12,000 miles per year), so doing an oil change every three months or so is certainly no big deal. Of course, I keep every receipt to document the fact that I am doing it more frequently than required by the factory recommendation.
I have used synthetic oil in my 2002 Nissan Sentra since it was new, and it is still humming right along with about 82,000 miles. I had two different Mustang GT coupes, a Ford van, a Toyota Corolla and a Nissan Maxima all perform flawlessly with Mobil-1 in the crankcase. I still followed the 3k drain interval, except for the Ford van.
That went for 5,000 miles between changes because I drove it as a work truck and put on 5000 miles every month, and I did not feel like changing the oil every other week. Once a month worked fine, as it was all highway miles and I put 200,000 miles on it in less than four years before selling it - with no engine-related trouble at all (although the tranny gave me some problems).
To coin a phrase from the Monkees, "I'm a believer." I treat every vehicle I drive as though I'll keep it for twenty years - even if I am not likely to do so. Aside from the peace of mind, a well-maintained car is going to hold its value better than one that has been abused, neglected or beaten half to death.
