i use QUAKER STATE - i figured someone would say exactly what you said but i had a ranger and i went to 300,000 and NEVER did anything major - this ram will do the same i like doin it and it dosen`t cost that much if you guy`s change your`s at 6,000 fine - if we all did the same thing it`d be a boring world but i bet some one some where is like me...
3000 miles on the nose for every vehicle I've ever owned. If its over the magical 200,000 miles or gets a regular "beating" it gets a bottle of Lucas. I also stick with the "diesel" type oils (Rotella anyone? ) and have never had a bearing failure. Lots of cars & miles & I probably wont change!
I'm thinking with the newer oils that 3,000k between changes may be overkill but its hard to break the habit! Anyone ever check out the "Bob the oil guy" website? I lost the address, but there was a lot of info there.
I had a 1988 ranger that I changed the oil between 5,000miles and 10,000miles.I gave it away at 384,000 miles(I used it for work and my wife convinced me that I shouldn't trust it any more) and it still only burned 1 to 2 quarts between oil changes.The oils and engine construction have become so good that you don't really need to worry about it.I am old enough that I can remember when if you changed your oil religiously and treated it nice most engines were worn out at 100,000 miles.There are even a few manufactures that now have oil change intervals as long as 8,000 miles. In the last 30 years I have not had a oil related problem but in the 60s and 70s that was a whole different story.The older cars that I have had that made it to the mid to late 80s without many miles will hit 250,000 to 300,000 miles with out burning excess oil or make the normal worn out noises.Sorry for being so long winded but as stated before unless you are racing or some other extreme use I don't think that you need to change it that often(unless you use it in a waste oil heater in your garage-ha-ha).
I run 3000 miles between changes. I might go over 300 miles at times, but I commute 100 miles four times a week to college. Yeah, 1500 is a bit of over kill lol. By the way, I use QS on the Ram as well.
I'm probably older than most on here but I remember changing oil and a lube job every 1000 miles. On my 96 I use Mobil 1 oil & filters once a year or 10,000 miles or which ever comes first.
On my 87 Valvoline oil & NAPA Gold filter at 3000 to 5000 miles or every year.
