TiiiMMMaHHH: going on 16,000 since i put in a 10k filter, lucas oil stabilizer, and 5w-20 synthetic. Added a quart a week ago just to get through the coldest weather. My car has 264k and counting, not even an engine knock. The oil stabilizer is the shiat. $11 well spent ($40 or so doing my own oil changes.)/Usually, I shoot for every 10k to 12.5k, just too damned cold and I'm lazy.//Drives 30k anually, usually highway mileage
Mister Peejay: Newsflash: If a shop charges $30 for an oil change and spends a half hour at $100/hour labor rate plus $20 in materials costs, how much profit is there in an oil change?On the other hand, changing the timing chains and guides at 60k because of lack of maintenance is very profitable./if we were interested solely in making money, we'd tell people to do nothing until it breaks
poorjon: I've got a Passat with the 1.8T. If you've got a VW turbo and don't make oil changes a religion, the engine will leap out of the hood and try to devour you./Maybe not getting a VW next time.
NFA: I work with a number of PhD mechanical engineers. One of which worked for Ford developing engine control systems for the Triton engine line. He claims that it is a well known fact among auto design engineers that many of the claims made by the synthetic oil industry are false. He said that there are research papers published showing that synthetic oil increases engine wear in cars driven in stop and go traffic but reduces engine wear when driven at highway speeds. He said he personally does not use any synthetic oils but uses standard mineral oils changed at 3000 mile intervals. He said if he does a lot of stop and go driving in unusually hot temperatures, he changes the oil more frequently.I've read the research papers but to be honest I couldn't make heads of tails of them they're written at a level beyond my engineering knowledge and comprehension.I've also spoken with Harley Davidson mechanics who have been wrenching for 30 or more years. They claim they see a higher rate of spun bearings in engines which use synthetic oil.I had a Jeep Wrangler which from the first oil change to the last, I used Mobil 1 synthetic oil. I babied that vehicle, never drove it hard and changed the oil myself religiously at 3000 miles. At 135,000 miles the engine stopped pumping oil the the cylinder head and spun a cam bearing. This happened in the 258 cubic inch inline 6 engine which is known to be virtually indestructible.
brandent: My Chrysler/Dodge dealer (for my van) is a complete screw up at service.
DemonEater: Plus they use awful cardboard Fram oil filters that leak dirty oil back into the engine, because they're cheap.
offmymeds: Bigger Leftist Intarweb Schlong: I go whenever the sticker on my windshield tells me to go. They also check and change all the other assorted engine fluids. Last time they replaced one of my taillights for me that I didn't realize was out, free of charge.I love my mechanic.This.We've been taking our vehicles to the same mechanic now since '99. Honest and reliable. That's hard to find anymore.
SacriliciousBeerSwiller: What pisses me off is when you get an oil change at a dealer and they put that little sticker on your windshield saying to bring it back in 3000 miles...even when the cars manual states that it should be every 5000 miles or whatever...and that dealer SELLS that same car. Seriously, scumbags and assholes, the lot of them...
brandent: Business Idea/Question.So the whole thing with the jiffy lube type places is to be fast and cheap right? Well that's because on a 3000 mile interval the whole experience is annoying and going to a dealer would be twice as annoying. The article (and pretty much any factual analysis) seems to indicate the average person really only needs 1 or 2 a year at most. It would seem that there is a niche for a higher end experience there. I.e. charging a couple hundred bucks and it's all inclusive. You get a nice waiting area. Maybe snacks. Your car gets an oil change, tire rotation, all applicable fluids filled or flushed. The car gets washed and vacuumed. A little scent. All the way up to a full detailing. Sort of a yearly refresh. I know these places exist but maybe they will become more popular and the insta lube places will go the way of the dodo.
thornhill: It's crazy that all cars don't have oil life meters like Honda sticks in their fleet (my Fit goes about 11k miles before it says the oil needs to be changed).Not to subscribe to conspiracy theories, but the only reason car makers give you a flat number in the manual of when to change the oil (as opposed to an oil life meter) is to create reasons for you to visit the dealer.
SpectroBoy: sigh..... this is why we can't have nice things.
DubyaHater: This is why I don't go to those JiffyLube places. I only go to the dealership for proper maintenance.

You and the lady check in, do your business, and we'll have your personal vehicle ready in the morning. (hotel contract with real mechanics, obviously)
Lost Thought 00: Is there an absolute time limit for oil quality? I rarely drive my car more than 3000 miles in a year, and I usually change my oil once a year. Could I go 3-4 years without changing oil given the same driving pattern?
Dear Jerk: Changing oil or plugging a flat are two things you should know how to do yourself, or sleep with a guy who does.**disclaimer: I will consider trading light automotive work for sex.
