Select 1980-2019 Vehicles Yukon Gear & Axle Gear 3 Qt. Penzoil 80W90 Conventional Gear Oil

This 3 quart bottle of 80W90 gear oil isn't matched to a specific Mustang or F-150 year range in our fitment data. It's a conventional, non-synthetic formulation designed for all types of differentials, so it works as a straightforward diff fill rather than a platform-specific part.

Why Upgrade to This 80W90 Gear Oil

• 80W90 viscosity in a conventional, non-synthetic formulation, not a synthetic blend, so you know exactly what's going into the diff.
• Formulated for all types of differentials rather than one specific design, so it's not locked to a single setup.
• Comes in a 3 quart bottle, ready to pour in for a fill or top-off.

Fitment Notes

This product doesn't carry a specific Mustang or F-150 vehicle match in our fitment data. It's filed as a general differential fluid rather than tied to a particular platform, model year, or trim. We don't have any fitment exclusions on file for it.

Install and Honest Talk

This is a gear oil, not a mounted part: there's no bracket, bolt-on, or drilling step to describe. It's conventional and non-synthetic rather than a synthetic blend, so if you were after synthetic-level protection or a longer service interval, this isn't that formulation.

Free US shipping over $99

Orders over $99 ship free by ground to the lower 48 states. Alaska, Hawaii and Canada are not included; shipping to those addresses is calculated at checkout. Some oversize or heavy parts (long-tube exhausts, bumpers, full lift kits) go freight instead of parcel: free to a commercial address with a loading dock, and residential freight delivery carries an additional charge.

When it ships

Parts ship direct from the distributor warehouse that stocks them, so dispatch timing depends on the part, not on a single cutoff. You get a confirmation with tracking as soon as it leaves, and tracking shows the delivery estimate for your address. If a part is backordered we email you an expected availability date.

Missing or damaged items

Report a short shipment or shipping damage within 5 business days of delivery. For a packing error, send us the date or package code printed on the label along with the part number so we can trace it with the warehouse.
