Can anyone give me an opinion for LIQUI MOLY High Performance Gear Oil (GL3+) SAE 75W-80.

Car is a Mitsubishi Lancer 1.5L with 4A91 engine and a Getrag 5 speed manual transaxle. According to the car's manual, it requires Dia Queen NEW MULTI GEAR OIL API GL-3, SAE 75W-80.

I was planning to order Red Line MTL, but as I have the car already in the garage, I have to get something that's immediately available. So what's your opinion about the oil I mentioned? Any other better alternative for a Getrag?

Do you care that the "High Performance" Gear oil is a Group III base stock?

Look at the MSDS sheets since Phillips 66 bought Redline.
I would just go ahead and buy the Liqui Moly, even though it is a group II fluid which Redline
now appears to be since being bought out.

The right question is should I care? I have read that some manufacturers don't recommend synthetic gear oils at least for some models. I think I read that on a BMW forum.

The question is what is best for the Getrag. By the way the car is at the garage because the gearbox was randomly making a grinding noise, like driving in reverse. A part of the gearbox (a spacer) at the end of one of the axles had worn out a bit and that axle was able to move a little. Except from the noise the 5th gear was jumping back and forth when I was pressing and releasing the throttle.

Since now I had used Motul Motylgear 75W-80 which is a GL4/GL5 and is marketed as semi-synthetic and Red Line MTL which is GL4 and synthetic. Both oils made the car shift better than the original oil, but didn't prevent the spacer from wearing out.

How can you tell which group does each oil belong to?
Here is the MSDS for the LIQUI MOLY: https://pim.liqui-moly.de/pidoc/P000229/4426-HighPerformanceGearOilGL3SAE75W-80-18.0-en.pdf
and here for the Red Line: https://www.redlineoil.com/Content/files/tech/MTL_GO_PROD_INFO.pdf

The links I gave above are not the MSDS files. My bad.
Anyway, here is the safety data sheet of Liqui Moly's High Performance Gear oil: https://sichdatonline.chemical-check.de/Dokumente/566/4426_0012_21-08-2015_EN.pdf

How do you understand which group does it belong to? I basically see "Baseoil - unspecified". Anything else that points to the answer?

When Liqui Moly says "Synthese Technology", it screams Group III. Voll (Full) Synthese is Group IV.

Thanks for the info!
Is there any specific reason to favor Group IV gear oils over III? Does always Group IV mean superior performance?

It's really the additive package. But for cold weather performance, Group IV tends to have a lower pour point.

Liquy Moly's pour point is -42 C. I think it's adequate for the vast majority of the planet.
If I try it, I hope that it will perform equally good with the Motul and Red Line gear oils, which made the car shift easier than the original oil, whatever that was.

I would stick with a GL-3 as specified in your manual. Here in the States, besides Liq. Moly, its hard to find a GL-3 and some transmissions like the GM used in my Slingshot also require GL-3. Somewhere I read that the newer specs, like GL4-5, can cause problems with some metal parts in the GM transmission (and perhaps other makes?). For that reason I used the brand sold by Polaris and is specified as GL-3. Point being, stick with Liq. Moly if thats what is avail in your area.

You know something? You have a point! Liqui Moly also produces a 75W-80 GL4 gear oil, but when using their oil selector they don't recommend their GL4 oil for my car.

Probably there is a reason for that!

But as I said both Motul GL4/GL5 and Red Line GL4 made the car shift easier. On the other hand, they didn't protect the spacer from getting damaged. I'm not sure I can blame them though. I have the feeling that other people with the same transaxle had problems, so maybe it's Getrag's fault after all and no oil could prevent the damage.

I have the same transaxle in both of my car, but these requires 75W90 GL4 as per the manual.
So that's what I used...Castrol syntrans Multivehicle, and recently switched to Syntrans Transaxle which is a GL4+ (they changed the formula of the Multivehicle and I didn't really like it).

I guess your car must be newer than mine, but so far no gearbox issue on my side with 75W90...and I guess Greece is a warm climate, so maybe going thicker for once... smile

Edit : GL3/4/5 is mainly for synchronizers (it's a balance, make synchos happy, or make geartrains happy) Like I said my manuals recommend GL4. One engine is the 4A90(I think, 1332cc), the other one is the old 4G15 but the gearbox are identical.

The transaxle is the F5MGA. According to the Liqui Moly oil guide your gearbox is F5MGB, the same with the 1.8L Lancer, if I'm not mistaken. Also Smart forfour uses one of these 2 as far as I know.

By the way I see that Liqui Moly suggests also the 75W-80 GL3+ gear oil for your Colt.
Motul also suggests a 75W-80 oil for your car. They only have GL4/GL5 gear oils though.

Here are some info about your gearbox: http://mitsipedia.info/index.php?title=F5MGx
