Redline or Lucas?

It is GL-4 like the MTL 75W80 many of us use,

MT-LV 70W/75W GL-4 - QUART
Popular in Toyota/Lexus LF 75W, BMW X-Drive and other transfer cases transfer cases calling for Shell TF0870
Recommended for Mercedes 235.10, Dodge/Fiat BOT 350 M3, GM BOT 303 mod, Toyota/Scion Manual Transmissions Gear Oil LV, VW/Audi and BOT270A Graziano Transaxle for Aston Martin, Audi & Lamborghini.
Offers quicker shifts, a perfect synchronizer coefficient of friction
Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
High performance gear protection and longer synchro life
Eliminates notchy shifting, even when cold
Low fluid friction to improve power transfer
Satisfies the gear oil viscosity requirements of 70W & 75W
Recommended for GL-1, GL-3 and GL-4 applications as well as where most special synchromesh fluids are specified

Well, I have just saved a small fortune. My Saturn Vue uses Dex 3 in the manual transaxle. I still don't quite believe it and will second/third source the data.

What year is the Vue? Ecotec engine?

It could be correct. My old Mazda MX-6 had ATF & when I was wrenching on Fords, all the fwd drives (Tempo's Escort's, etc) all used ATF in their manual transmissions. Even the GT Turbo Probes. I think if my Mirage was a standard, I would be tempted to try ATF in the MT5 to see if MPG improved. (Ducks for all the rocks that will be throwed at me after this ) We don't have Hypoid gears, so do we really need the heavy gear oil??? Just thoughts...

I drained my factory manual fluid at 30,000 miles, & I thought it was quite light for manual transmission fluid. The Redline MTL synthetic oil seems pretty thin to me as is. I planned on doing a 2nd change when my Mirage reaches 80,000 miles this summer. The factory oil looked so good & clean @ 30,000 miles, & I figured 50,000 miles is more than safe.

I had a motorcycle mechanic once ask me how I kept my chain & sprockets looking so good, because I never needed to change them on my old motorcycles. I had a soup can with 80W-90 gear oil in it with a small paint brush. About every other gas tank, I would pop the rear tire up on the stand, let the chain run at idle, & drench it with oil using the paint brush. My rear rim didn't always look the best, but my chains lasted forever. I know there are chain oils that are sticky, but I found thick gear oil to work the best.

I'm not a fan of thin oil. I won't even put 0W20 in my Mirage engine any more. Heavier oils are OK in other markets. The lighter oils are driven by fuel economy, but I haven't seen any difference in using 5W30 full synthetic oil.

2007, Ecotec. 2.2

Even when I owned bikes that were hard on chains, ie. 1973 Kawasaki ZR1 903cc, 1972 Kawasaki H2 750 triple, and I rode them hard (wheelies on the the interstate @75mph were done stupidly but often, many times with a passenger!!!) The owners manual called for all sorts of weird things, boil the chain in grease, etc.

My Z1 with pipes and airbox mods and other things would run 1/4 11.1 sec @ 133mph. It was a rocket. did 1 run 10.6 @ 141mph

Anyhow, I only ever used Castrol chain oil from a can. It was dripped on from a long plastic nose.
