Redline Gear Oil: Lots Of Options To Tune Your Diff
By Rick Reimundez
If you’re running a specialized differential — or want to eek a little more life out of the one you’ve got before ditching it for a fancy performance model — Redline can help. They offer a wide variety of gear oils, including hard-to-find multi-viscosity options that’ll help you tweak performance.
First the standard marketing pitch of every oil manufacturer: diffs take a lot of abuse over a wide temperature range, and heat is the enemy of all gear applications. Too much heat breaks down the oil and prevents it from lubricating properly. Redline claims — like everyone — to reduce differential and gearbox temperatures.
But forget the claims. Redline’s viscosity options give you a fighting chance if you live outside of the happyland where engineers test cars. For example, in colder weather, you can swap a regular 90 weight gear oil — which can take up to five minutes to flow to the bearings at -15 degrees F – with Redline’s 75W90 only, which requires a second. This is also advantageous if you make a lot of short trips, as the multi-weight oil reaches operating temperature more quickly, offering full lubrication sooner.
Red Line also manufactures a selection of gear oils that work with limited slip differentials without the need to add a separate friction modifier, though they also make a friction modifier if you want to use it with another oil.
Redline gear oil ships in one-quart bottles for around $10-12 – though sometimes you can find deals locally. It’s available at pretty much any auto parts store, or anywhere motor oil is sold.
