Semi-synthetic 20W-60 for powerful and tuned classic engines

Millers Classic Sport 20W60 is an extra high-grade semi-synthetic SAE 20W-60 multigrade engine oil, with performance additives and viscosity-index improvers for higher protection at competition temperatures.

It contains full ZDDP (zinc/phosphorus) and is sold in 1 L and 5 L packs.

Choosing the right oil

The 60 in 20W-60 tells you this is a thicker oil at operating temperature than a 20W-50. It is for engines that run hot or hard: Millers Oils names Aston Martin, Jaguar, Ferrari, Lotus and similar engines with high specific output, high-grade classic engines, and tuned vehicles that need extra protection beyond a 20W-50.

If your engine is in standard tune and its handbook names 20W-50, going thicker is not an improvement in itself; the extra viscosity can mean higher oil temperatures and slower oil flow when cold. Choose the 20W-50 sibling unless there is a clear reason such as competition use or an engine builder's recommendation.

Competition temperatures are the stated target, so this suits track-day and race use more than a Sunday-drive classic.
