the SEVERE GEAR is GL-5 and not safe for synchros , could make for difficult shifting and damage internal parts . The MTG is fine , states that here under PRODUCT DESCIPTION www.amsoil.com/storefront/mtg.aspx . Mentions TOYOTA as well .

I think I'd stick with the GL-4 as well.

used MOBIL 1 ( 75w-90 , GL-5 ) in the 2000 PRIZM ( Corolla ) with a speed manual which is similiar to that of the YARIS and threw of the synchros making for grinding when shifting to different gears , downshifting , and the clunk / harder engagement ( grinding ) into reverse worse . When replaced with the REDLINE MT-90 ( GL-4 ) all that disappeared . As for when using the MOBIL 1 synthetic tranny fluid for the power steering in the PRIZM ( Corolla ) it worked wonders . Removed the old P.S. fluid after car sat overnight to withdraw and refill fluid at COLD mark of resorvoir with a animal medicine dispenser ( oral syringe : http://www.drsfostersmith.com/produc...cfm?pcatid=836 ) with a clear plastic air hose ( air pump for fish tank ) attached to syringe ( slips over end ) and drawed out as much of the old / mixed A.T. fluid as possible over period of time until most of the MOBIL 1 A.T.F was gone . That way it would clean and replenish with new fluid over time . The amazing part is that when the regular P.S. fluid in the power steering resorvoir ran hot it would read at or a bit over the HOT mark . When applied the MOBIL 1 synthetic A.T. fluid it read a little over halfway point , COLD mark , when hot ( less friction = less heat = less expansion of fluid ) . AMAZING . NO leaks ( checked often ) . The steering became more responsive ( like that of electric power steering ) and with less effort at slow speeds ( inertia ) . When turning the wheels at a standstill there was no squealing as well . I think it may have helped with gas mileage due to less resistance in turning ( less gas applied to turn , coast ) . If you look in YARIS owners manual it states that one of the benefits of electric steering is for fuel economy . If not mentioned in YARIS owners manual , it did state it in our '07 PRIUS owners manual that was traded in for '08 YARIS sedan . So , if have an older car with A.T. fluid for power steering I highly suggest the MOBIL 1 synthetic A.T.F. ( or other ) for use . I think you'll be quite pleased in the steering performance .

during this time of using MT-90 and MOBIL1 A.T.F. for power steering the PRIZM got a little over 43 miles per gallon . The conditions were : 70% hwy. / 30% city ( speeds up to 70 m.p.h ) , 2 people 90% of time , hot and humid , Tire Pressue : 34 P.S.I. ( Cooper Trendsetter SE ) , GULF 93 octane , and a dose of CHEVRON Techron . The motor oil was regular PENNZOIL 5w-30 . The miles were from looking at '08 YARIS and COROLLAs . The gas mileage that fill is very close to both our '08 YARIS ( automatic sedan and 5 speed manual L.B. ) for best fuel economy . They're best so far has been a little over 44 m.p.g.. Miss that car . Traded in for the '08 Liftback with 5 speed manual . The clutch was easier in that too .

So Redline MT-90 is the best for tranny, better than AMSOIL?

I'd say the MT-90 and Amsoil's GL-4 75W-90 are both close and very good, probably both are better than my Pennzoil GL-4 75W-90, but I wouldn't care to breakup the theme that I got going on.

PENNZOIL now has a GL-4 synthetic gear oil , http://www.pzlqs.com/Tech/Pdsheet/Do...E75W90GL-4.PDF and http://www.pennzoil.com//products/ge...#SyntheticGear , wonder if this is as good as their PLATINUM motor oil that gets very good U.O.A.s at www.bobistheoilguy.com . May have to give this a try in the future . Should cost less than AMSOIL or REDLINE , may be difficult to find . Sorry to break the mold . Couldn't resist .

Still waiting on Napa to give me a call when the Pennzoil comes in...they said 1 week, which I think would have been the 13th.

Hell, old 3rd-gen Civic manual transmissions recommended 30W engine oil in the transmission, and the engine if you lived in temperate and mild climates. Made it insanely-cheap to just change all the fluids every oil change, since 30W is just about bottom-barrel for price.

give us the scoop once it's been installed . May want to give it a try myself over time . Keep seeing very good U.O.A.s for the PLATINUM motor oil at B.I.T.O.G.. Would think their synthetic gear oil be a good performer too . Hang in there . |
