Bio-Synthetic Engine Oil 5W-30

Renewable Lubricants 85121 is a bio-based engine oil formulated for gasoline engines in light duty trucks, passenger cars, and SUVs. It meets API SN/SM and ILSAC GF-5 standards and carries a Dexos 1 rating. The 1-quart bottle contains detergent additives with oxidation and viscosity index inhibitors.

Sustained Protection Under Load

The bio-synthetic base formulation maintains viscosity stability during extended operation. Oxidation inhibitors resist thermal breakdown while viscosity index inhibitors preserve film strength across temperature ranges. Detergent additives continuously suspend contaminants to prevent sludge formation during prolonged use.

Specification Boundaries

This product is limited to gasoline engines requiring SAE 5W-30 viscosity grade. It does not meet specifications for diesel applications or viscosities outside the 5W-30 rating. The 1-quart container suits top-off needs but requires multiple units for full crankcase fills. Biodegradable formulation aligns with environmental considerations.

Questions about this item

How hot does the 5W-30 bio-synthetic oil run in a light-duty truck engine during all-day operation?

The 5W-30 viscosity grade maintains stable lubrication across normal operating temperatures for gasoline engines in passenger cars, SUVs and light-duty trucks.

What vehicle specifications must I already have for the 85121 engine oil to be compatible?

Your vehicle must use a gasoline engine and require an SAE 5W-30 oil meeting API SN/SM, ILSAC GF-5 and Dexos 1 standards.

Will the bio-based formulation with oxidation inhibitors protect an older gasoline engine that previously used conventional oil?

Yes, the detergent oil with oxidation and viscosity-index inhibitors is designed for gasoline engines and meets the same API and ILSAC ratings older engines specify.
