EVERYONE should be running synthetic.

The wife just went from Salem to Seattle this weekend and got 34 mpg. We have started running a quart of two stroke oil in each tank and the mpg has gone up 1-3 mpg depending on city or highway.

One interesting point; mine runs better with 10w-30 semisynth (assembler
recommended) meaning, it dont burn ANY oil during trip from one oil change to another, nor push it from any seal. When i used once 5w-40 Full synth,
it burned about half litre during one trip, and pushed it little through one seal.
Unhappily i need to use that 5w-40 since winter, 10w-30 wont work on winter
very good. And sound is smoother with 10w-30 semi-synth.
Its truck oil by the way^^. But i wouldnt never drag my hands into mieral oil, big no no.

I think Tom Bryant recomends 5-30 synthetic. I'm running 5w40 Rotella synthetic in my car. I just did a 600 mile round tip, and probably burned about a quart of oil. I was running pretty hard though, doing 75 to 80 mph. Even with the oil seperator, I think a large part of it is going into the intake. I'm planning on stuffing it with some steel wool.

Average mpg was 34. Not bad for cruising as fast as I was. I would expect I would get 36 or better if I was going 60 to 65.

I used Amsoil Series 3000 5W30 in the '85 wagon when I drove it across the country over the summer (Boston to Seattle). It never used a drop except for the day I drove from Missoula, MT to Seattle -- climbing several major mountain passes in western Montana and Idaho in 100F heat with a massive load in the car caused oil temps to shoot sky high, and the 5W30 must have just gotten so thin that a bunch slipped past the rings and valve guides. I was down about 3/4 of a quart at the end of that day. If I had had a proper oil cooler rather than the dumb VW coolant heat exchanger in the car I think things would have stayed better under control, and I might run 15W40 Amsoil marine grade oil in the future during the summer since my cars are often subjected to very hard mountain driving with big loads in hot weather.

Starting to prepare the 745 for another long trip, from Seattle down through Wyoming to New Mexico then back via LA and up through California, in the middle of January. Will probably run 5W30 for that one.

Ya I'm not sure how much is being burned and how much is just sucked into the intake. My car has got 170k miles so I'm sure its burning some oil anyway. If I drive it normal throughout the week to and from work it doesn't burn any oil at all, but an evening of hard driving messing around with it and I can burn some...
Is that Amsoil 3000 a diesel rated oil?

The Series 3000 is the best lightweight diesel oil on the market. Good thing too, since it costs an arm and a leg... you need $80 worth to do an oil change on a D24T! Add in a good filter and oil changes are nearly a hundred bucks. Good thing you don't have to do em that often...

Except for those of us that drive 3000 miles every month and a half ... I drive from Eugene to Portland and back just about every weekend. $100 is quite a lot to have to spend every 2 months or so. I'm at 3300 miles on this change so far and I'm hoping I can just afford an oil change before January when I get my next installment of money from school..

I'm seeing 34mpg on my D24. Not bad for how bad it's running.
