CalBest Supplies Mobil 1 Synthetic Gear Lubricant LS 75W-90 6 × 1 Quart | MPN 1043611 Grade SAE 75W-90 Specification API GL-5 Quantity 6 × 1 Quart Ships From Azusa, CA Six quarts of Mobil 1 gear lube, shipped free.
Mobil 1 Synthetic Gear Lubricant LS 75W-90 is a full synthetic gear oil for differentials, final drives and transfer cases that call for an API GL-5 lubricant. The limited-slip friction modifier is already blended in, so a clutch-type limited-slip diff does not need a separate bottle of additive.
This listing is six 1-quart bottles, Mobil part number 1043611. Most differentials take between 1.5 and 3 quarts, so six covers a front and rear axle on most trucks, or two rear-end services.
Buying more than one? Volume pricing is already set on this listing — the price per case drops automatically at 2, 3 and 4 units. We also list this oil in a 12-quart case. What Mobil publishes about it The limited-slip additive is already in it Mobil describes it as giving “excellent limited-slip performance — helps to reduce chatter and improve traction.” Check your service manual, because some manufacturers still specify their own modifier. Holds its grade across the range Viscosity index of 146, with a pour point of −39°C. It stays pumpable on a cold morning and still carries load at temperature. Protects copper alloys Mobil lists “excellent rust, staining and corrosion protection of copper and its alloys.” Worth knowing if your axle has bronze thrust washers. There is only one Mobil 1 75W-90 People often hunt for a “non-LS” version. It does not exist — Mobil makes this and the 75W-140, both LS. If your manual says 75W-90 GL-5, this is the one. Where it goes
Mobil recommends it for these applications where an API GL-5 gear lubricant is called for:
• Conventional and limited-slip differentials • Front and rear axles • Final drives • Transfer cases • SUVs, vans and light trucks specifying SAE 75W-90 GL-5 Not a transmission fluid. Mobil states plainly that it is “not recommended for automatic, manual or semiautomatic transmissions for which engine oil or automatic transmission fluids are recommended.” If your manual gearbox calls for a GL-4 oil, this is not the right product — message us and we will point you at one that is.
