unless it is a harley bathed in it's own oil mist and not normally driven in the winter.

for me, expensive oil = less money for beer!

b.t.w. i use valvoline in all my stuff, bike included. buck and a half a quart. however, i do use synth gear lube in the differential. 75w140, six bucks a quart at farm and fleet.

you guys can have the 40 dollar oil changes, thats 4 cases of beer!

That's why I don't live in Detroit anymore.
In my stable is a all original unrestored 1970 Pontiac LeMans Sport convertible.
1975 GMC Jimmy it's a toy and I did do rust repair because it came from a rusty place)
1988 Suburban with 72k and NO Rust
1989 Honda Accord with NO rust.

We pay cash for vehicles and we don't like Air bags so all our vehciles are older and with the exception of the Lemans that I am about to start a restoration on, all our vehicles are regular drivers year round.

John you just live in the wrong place! You should move south and then you can drive you hog in December like they do down here. Plus it's closer to Daytona for Bike week.

My truck has Amsoil 5W30 in it's crankcase, and I changed the rear end lube at 3000 to Amsoil.

I have hear others say on pickuptruck.com that through oil tests, Mobile 1's additive package is shot at 4500 miles. I tried Mobile 1 on one change, with a brand X filter for 3000 miles, then changed it to a Mobile 1 filter. At 4500 miles the oil was very dirty. It might have stayed cleaner if it had a Mobile 1 filter to start with.

Most miles I have gone on an Amsoil change is 10K, since that is the mileage I put on in a year.

John,
Funny timing, the May '03 issue of the Amsoil Action News has an article on Amsoil 20W-50 synthetic motorcycle oil vs Harley Screamin' Eagle 20W-50 syn. motorcycle oil.

Craig,

I read that very same article as well with a great deal of interest.

craig,

believe it or not, you do not want to use too slick of an oil in a harley.

they are roller bearing engines, the super slippery stuff makes the rollers skid instead of roll. you'll wreck your engine in short order.

last time i was at the factory i saw the drums of valvoline 20w50 they were putting in new motors. (not that i care what the factory does anyway) they said they use shell also.

most guys who pound harleys use aviation oils, usually areo shell 100w with excellent results.

when it is hot out i also use straight 50 or 60w valvoline. much thicker than that and kick starting on cold mornings is almost impossible.

i have used kendall 50 and 60w with good results too.

back in the 50's harley recomended adding kerosene to the oil to thin it out for below 10 deg. riding.

about a pint to a gallon.

it was done to keep ice from clogging the oil tank.

bet the current crop of psedo bikers wouldn't try that!

might get their designer chain drive wallets frosty!

Question: Could I use synthetic gear lube in my limited slip differential in a Ford Explorer? Would I need to add an additive for the limited slip?


Secondly, I would not recommend using aviation oil in a Harley, or any other non-airplane. Airplanes...

- burn lots of oil so carbon buildup is prevented by using "ashless" oil, leaves less residue upon burning
- have their oil changed every 25 or 50 hours of use, so they only use dispersants, no detergents

I have owned a dozen airplanes and believe me "aviation" does not necessarily mean "good", just different.

dmac,
Sure you can use synthetic gear lube with your limited slip. Amsoil says you do not have to use an additive with their 75W-90 gear lube while Mag-Hytec (sold me the finned aluminum extra capacity rear differential cover) tried to sell me additive with another brand of synthetic gear lube. I haven't noticed anything different and have run the gear lube for 13,000 miles now. I would follow the manufacturer's recommendation for the gear lube you use. I put Mobile One gear lube with an additive in my '92 Z71 because it was recommended.

John, not only have I learned a bunch about our Airstreams but I keep picking up more info on this forum than I ever dreamed of. I can't afford a Harley and dmac, I can't afford an airplane so you guys just cut it out with too much information. Just kidding!
