Sure the oil is garunteed for 15k, but how long is the oil filter you’re using good for? ---

> [@Onyx Z32](#): > > Sure the oil is garunteed for 15k, but how long is the oil filter you’re using good for? wait, your supposed to change the filter???lol j/k I never even looked into the filter life span. It is a purolator and to be honest im not too crazy about it. Its hard to find a good filter ofr my car at the local parts store. I just need to order a bunch from pelicanparts so i have them at hand. hmm, maybe ill just change the filter. Its a cartridge style and takes about 30secs to change on top the motor. When i look at the oil it looks, smells good.:shrugs: Doesnt look too contaminated. I think im just gunna change both. I dont see any reason to risk it. has anyone else ran this oil to 15k??? ---

i’m using that oil and a k&n filter also guarenteed for about that long i think…but i still change at least every 5k miles, which is still too much i think, most people recommend i change mine every 3k miles, and i’d rather not take ANY chances with my car… ---

I use extended performance in my car. Usually change around 5-7, but have let it go til 10-12k on occasion. Was still good when it came out too. ---

> [@fairgentleman Z](#): > > Because I drive my car harder in two days than most forum members in two years. i don’t care if you held your engine on a dyno under load at 7000 rpm for 33 miles that is a waste. your not going to break down the lubercation properties of a oil in one hour of use unless your engine is damaged and has massive blowby and coolant in the oil. ---

The 33 miles was an extreme case, as my O2 sensor is/was bad and I was averaging 4~5 miles per gallon mostly idle time in grid for auto-X, and the oil smelled a little gassy.

you probably know but if you have a O2 sensor that is bad the car will actually run better with the sensor disconnected. that may be a ford thing but bad O2= disconnect it dirty/bad maf disconnect that. it just makes you run a bit rich… ona ford at least. ---

I don’t know what I’m going to do anymore… I bought my car with 49K on it; car ran great. Switched to Mobil 1 right away, and started K&N filters at 60K. I was changing the filter/oil every spring when the car came out of storage, and was only putting about 5-7K on the car every season; when I put more than 7K it got another oil change. But… When I pulled the motor at 97K miles… Every journal on the crank was scored; multiple severely. Not sure what caused this; but I’m leary of K&N filters now; that’s for sure. ---

I had a bad O2 sensor on my probe and it ran like total ass, it just bogged down and died afer 3k rpms. ofcorse it had other issues also so…there ya go. ---

I don’t think anyone on this forum should wait 15k miles with their driving habits. I’m using Mobil 1 extended and I change every spring and fall. If you’re changing your filter you might as well do oil while you’re under the car. ---
