Quaker State 75w-140 synthetic gear oil

QUAKER STATE® FULL SYNTHETIC SAE 75W-140 GL-5 GEAR LUBRICANT is a thermally stable gear oil engineered to exceed the most severe performance requirements for passenger cars, sport utility vehicles and light-duty truck differentials (including limited slip), manual transmissions and transaxles calling for an API GL-5 lubricant. It protects against gear wear and spalling, even during heavy loading. It is ideally suited for use where extreme conditions exist or where an extended service interval may be encountered.
Because it is made entirely with synthetic base stocks, QUAKER STATE® FULL SYNTHETIC SAE 75W-140 GL-5 GEAR LUBRICANT offers excellent performance when subjected to temperature extremes – both high and low – for year-round protection under a variety of conditions. It is especially effective in vehicles operating under severe conditions, such as towing a boat, trailer or other vehicles. It is also effective in promoting smooth shifting of manual transmissions and transaxles where extreme low temperatures are a concern. The synthetic base, combined with advanced additive technology, offers outstanding resistance to oxidation for long lubricant life and minimal deposit formation for clean gear operation.
• Exceeds requirements of API Service Designation GL-5
• Meets major vehicle manufacturers’ specifications
This product contains special additives to:
• Reduce bearing and gear distress under extreme operating conditions
• Protect at both high and low temperature extremes
• Resist oxidation to retard deposit formation
• Guard against “chatter” in limited slip axles
• Protect against rust and corrosion
• Minimize foaming

Quaker State 75w-140 synthetic gear oil

I tow a boat with my JGC, so the manual staes to use a heavy duty 75w-140 in the rear differential. The only one around was this quaker state stuff.
It is clear in colour and can be loaded into the rear differential with one of those boat outdrive pumps , about $10 at your local car or boat dealer.

The differnetial was easy to open , with only a rubber plug to open the thing up.
Took out the old fluid and then pumped in this stuff , about 1 3/4 liters before the fluid started to come out , oh and one thing I did not know -- add the friction modifier a 4oz bottle 120 ml from your dealer $5 mopar so as to make the LSD limited slip differential work --- back differential only unless you have quada drive then in both difs. The front diff uses 75w-90 synth by motomaster

mine is selcta drive with lsd rear.

So far it's worked great , towed my boat with no problems and am quite happy with the product -- I'll report back in about a year with an update

June 2008 -- stuff still running good in the diff, maybe I'll do a second time , if I get round to it
