Product Description
Service Life For product service life in differentials, consult your owners manual or the Original Equipment Manufacturer (OEM) to establish the application, NORMAL or SEVERE.
For product service life in non-differential applications, consult owners manual or the OEM for either normal or severe synthetic oil service intervals. Where service intervals are unavailable, drain at twice the interval for conventional oil. Note: AMSOIL does not support extended drain intervals where water contamination occurs. Check and service the gear oil frequently when water contamination is possible. Gear oils should be changed more frequently when operating vehicles or equipment in dusty or dirty conditions unless the gear system is properly sealed and equipped with membrane type breathers. AMSOIL SYNTHETIC 80W-90 GEAR LUBE is compatible with synthetic and conventional gear oils, however mixing oils reduces the benefits and nullifies the extended service life recommendations. AMSOIL 80W-90 SYNTHETIC GEAR LUBE is compatible with most limited slip differentials. If limited slip differential chatter occurs, add AMSOIL Slip-Lock friction modifier additive.
AMSOIL Synthetic Gear Lube Recommendations AMSOIL has optimized gear lube performance for specific operating conditions. However, AMSOIL gear lubes are multi-functional and may be used in many different applications. This chart conveys the best AMSOIL recommendation based on product design and operating environment. First row product recommendations offer superior performance in the respective applications. Second row product recommendations offer excellent performance in the respective applications. The third row is exclusive to SAE 80W-90 viscosity. AMSOIL Severe Gear® 75W-90 (SVG), 75W-110 (SVT) and 75W-140 (SVO) synthetic gear lubes have a performance emphasis on the extreme pressure and high heat of todays vehicle differentials. AMSOIL Long Life 75W-90 (FGR) and 80W-140 (FGO) synthetic gear lubes have a performance emphasis on 500,000 mile extended drain intervals associated with larger sumps and lower operating temperatures of over-the-road truck differentials. AMSOIL 75W-90 synthetic gear lubes will outperform conventional 80W-90 gear oils in all applications and may be used as a replacement.AMSOIL offers 80W-90 (AGL) synthetic gear lube for those customers requiring this specific viscosity grade. * Abbreviated Version HEALTH & SAFETY Click here to view the MSDS Data Sheet for AMSOIL AGL.

BMW R1150 GS MotorcycleI have been using the Synthetic 80W-90W Gear Lube in the Transmission and Final Drive unit of my 2001 BMW R1150GS motorcycle or years. It never breaks down between changes even though I ride in 1st and 2nd gear for hours on Utah desert roads for hours at a time. shifting is always silky smooth. I highly recommend Amsoil Synthetic Gear Lube wherever the motorcycle specs call for Gear Lube. If your Transmission also houses a "wet clutch" be sure to research the correct Amsoil product to use with a "wet clutch" as there is a special requirement to insure that "wet clutches" won't slip.

Gear oilIt's a gear oil... I just poured it in about a week ago. Can't really say anything yet. I suppose it does what it should. I actually overfilled the rear differential because my truck was on the hill when I changed the oil, so I wanted to make it right and parked on the leveled surface today and unscrewed the fill plug. About 6 oz of oil came out. I noticed its color and translucency changed after a week of driving. It was noticeably darker. About 150 miles. But to me it means that synthetic stuff cleans the dirt and residue that was left there from my old conventional oil. I might need to do another differential change shortly then I expected. But after that second change - I would leave it alone for a loooong time.... Item Reviewed: Synthetic Gear Lube SAE 80W-90 (AGL)
