I would add more, but the poll only let me do one. I have 3 trucks and they all get their oil changed at different intervals.
I change my oil every 3K with Valvoline Max Life, and a Purolator Pure One filter. I was using the synthetic blend, but switched to full synthetic Max Life. Valvoline still recomends following your manufactures intended oil change intervals, so I'll still change it every 3K. I might add that I can actually tell a difference in the operation of the engine with full synthetic. The old beast really seem's to be running smoother.
I change mine every 5000 using full synthetic (Mobil 1 for now) and a NAPA Gold (Wix) filter. I think I am going to switch to the Valvoline full synthetic since they offer the 300,000 mile warranty (probably a scam anyway) because I am going to need this truck to last a long time. At the rate I drive, it will have almost 200k on it when it is paid off.
I certainly believe in frequent oil changes for any vehicle that is worked hard. I do 5K between changes but my truck is basically used a car. I also seem to think that mine is smoother on full synthetic. This may be just my perception but if it pleases me.. then so be it!
Same here. I have been known to get my oil changed on a really long trip ...if I have been driving it really hard. I will also sometimes have it changed if I am heading back home from 1500 miles away and plan on really running it hard to get back home. I have been known to drive 24 hours at a stretch, stopping only for fuel and eats. Darling Wife hates it when I do that. For example... Last summer we left Fort Worth...drove up thru OK and Kansas into Nebraska... turned west on I-80..went over into Wyoming and took I-25 up to Billings Montana before stopping. Thats right at 1,500 miles. Part of it at more or less legal speeds. Part of it at 100 mph +. Only stopping for fuel and food. That would probably be considered severe service... So...in summary... I change the oil depending on how I have been using the car...always trying to err on the side of caution.
Even if you use the expensive stuff, oil is pretty cheap insurance against major engine failure. Sometimes the stuff we do just makes us feel better about it... so what?
My feeling exactly. If it makes "ME" feel better about changing it...that is really all I am concerned about. I don't care that the greenies think I am wasting resources. Talking about major engine failure...I read that replacing the NorthStar engine with a "NEW" one will run somewhere in the neighborhood of $8,000 bucks. I can buy a heck of a lot of oil to make it run longer for $8,000 bucks.
