I increased my actual mileage (4x4 '96 Tahoe) by 2 mpg in both city and
highway simply by putting synthetic lubricant into every available orfice
(the Tahoe's). Including differentials, transfer case, engine,
transmission, power steering pump, you name it. I get 19 on the road when
running between 70 and 75, over 75 it starts to fall off prettly quickly.
If you tow (I have an open trailer and either a BSP 240Z or an AP RX-7) the
mileage is 15, being conservative and 13 if you are silly. YMMV. It's a
1500 series with the "Vortec" 5.7 engine. I am not happy about the rear
spring rate, when I put on new shocks it'll get "helpers".
Oh, my $50.00 (that's right FIFTY dollar) RX-7 cranked right up and purrs
like the mean kitten it will be, someday soon. Bank auctions ARE wonderfull
things. Almost wish I hadn't torn all the interior out prior to starting it
up.
