Actually any SM-rated dino oil is pretty stout stuff and good for 5000 miles under most circumstances.

I drive apporx 2 thousand - 3 thousand miles per month on my trac. Any sugguestions on oil.
If you want to lessen how often you change the oil use either Mobil 1 Extended Performance or Mobil 1 Truck & SUV, just keep it topped off and it'll be good for 10,000 miles. We ran M1 EP in my dad's Cadillac, which admittedly holds 7.5 qts, until the oil life monitor was down to 4%. That made 11,200 miles :blink: on the oil, no filter change, sent the used oil to Blackstone and they said it was fine.

Question: Does anyone here know what the percentage of oils ( synthetic vs dyno) that are in these blends? I have always stated that 1% synthetic still qualifies as a "synthetic blend". I have not been able to find this information anywhere.
It will be on the MSDS for the oil. Usually you can find it on the oil company's website and some are posted at the BobIsTheOilGuy.com forums. Note, if you go to BITOG.com don't jump in with your first post asking "What oil should I use?". For gawd's sake use the Search or prowl around a little first. The regulars there have only seen that question 30 bazillion times already and they get kinda pissy about it.

Is there a different filter for the blend?
No, Motorcraft, Purolator PureONE, NAPA Gold are all fine filters. Mobil 1 or K&N if you want to spend more money, I'd use those if you want to go 10k on the oil. They have synthetic filter media, not paper or a blend, and will hold up better over the long haul. The pores in paper filter media are not uniform by nature so there is an inheirent compromise. With synthetic media you can make the pores uniform to whatever standard. All that said, personally I don't get real excited about it, I use Motorcraft filters and the occasional NAPA Gold if I happen to be passing by the NAPA store near oil change time. I change every 5000 on the car and Trac, 3000 on my decrepit old Astro work van because it needs all the help it can get. :lol:
