Description

Redline 80W250 GL-5 Gear Oil (Gallon)

Redline 80W250 GL-5 Gear Oil is the newest addition to Redline’s GL-5 lineup. It’s built for applications that need an SAE 250 gear oil. It also suits cases where a 140-grade oil no longer gives enough protection. As a result, it suits some of the toughest differential applications on the market.

This gear oil works as an alternative to Redline Heavy ShockProof in problem nitro drag race differentials. It’s also popular in Model A and Model T vehicles. It suits other antique or classic cars that call for 600W gear oil. Additionally, it reduces noise levels in Morgan 3 Wheeler bevel boxes. It also excels in off-road applications that require an SAE 250 oil.

Like the rest of Redline’s GL-5 range, this gear oil uses fully-synthetic, polyol ester base stocks. As a result, it holds up well under extreme pressure, and it resists oxidation better than conventional gear oils. Its high viscosity index also keeps film thickness more consistent as temperatures change, and it exceeds API GL-5 specifications. This gear oil is compatible with petroleum and other synthetic gear oils already in your differential. Extended drain intervals and reduced wear are common benefits across Redline’s GL-5 lineup.

Typical Properties

  • API Service Class: GL-5+
  • SAE Viscosity Grade: 80W250
  • Viscosity @ 40°C: 520 cSt
  • Viscosity @ 100°C: 52 cSt
  • Viscosity Index: 165
  • Pour Point: -24°C (-11°F)
  • Brookfield Viscosity @ -26°C: 1150 poise

Because 80W250 is such a specialized grade, Redline only produces it in a Gallon size. Always confirm your differential calls for SAE 250 before switching to this heavier grade. Redline 80W250 GL-5 Gear Oil is a suitable replacement wherever SAE 250 is specified. It also works wherever AGMA 7 EP or ISO VG 460 is called for. Not sure if it’s right for your differential?

★★★★★ Good part, freight took an extra day
Hemi R · Gisborne · Example review

Rural delivery so it was two days not one. The part itself is mint and the oil was in the box which I did not expect.

★★★★★ Exactly as described
Sarah M · Dunedin · Example review

Price was the price, no surprises. Return pickup was already booked which made life easy.

★★★★★ We fit these for customers every month
Workshop customer · Christchurch · Example review

Order before 2pm, on the bench next morning. Preload sorted so we do not see them back. Saves us a hoist for a week every time.
