Millers Oils For Your Classic Car

When you own a classic motor, it’s critical to select an engine or gear oil that has been specifically formulated for a classic vehicle and its components, rather than a standard modern oil. This is because classic vehicles have unique features not found in modern cars, such as lower revving, hotter engine temperatures and greater metal-to-metal tolerances. They can also feature rope or cork seals, and might have excess carbon build up making their lubrication needs unique.

One of the things that makes classic oils different is that they have a higher viscosity. This means it is more resistant than modern oils, offering improved oil consumption and a lesser chance of the bevel gears and cross shafts flinging it off. Furthermore, oil seals are less likely to leak when the oil is of a high viscosity, saving you from a possible major problem.

The other important feature of classic car oil is the anti wear additives. Historically, car oils contained a zinc and phosphorous compound known as ZDDP, but due to its effects on exhaust emission systems, the mixture was phased out and engine designs were altered so that it was no longer required. Unfortunately, the newer oils can cause substantial damage to classic vehicles which is why it’s critical to use an oil based on the original formula.

If you’re wondering which classic oil brand to go for, we recommend Millers Oils.

Millers Oils was founded all the way back in 1887 by John Watson Miller, although at the time it was called Millers Bros. It was, and still is, very much a family run business, and has played a major role in transportation lubricants over the years. In fact, Millers Oils were the first producer of long drain interval oil for trucks, and also produced the first diesel specific engine oil for cars!

What we offer

We currently stock three types of Millers Oils – Engine, gear and worm steering wheel.

Engine Oil

Pistoneeze mineral oil is a monograde oil designed for veteran and vintage cars built up to the 1960s, but can also be used on cars built up to the 1930s if you feel confident that no dirt or debris has accumulated in the crankcase. Featuring moderate amounts of detergent, this mineral based oil provides excellent engine wear and anti oxidant protection, and remains at the right consistency even in the higher temperatures often seen in classic engines. We currently stock SAE 40 and 50.

Gear Oil.

High viscosity gear oils are essential for protecting your gear system from wear. We offer a number of different gear oils, including EP 140 GL4 which is designed to stand up to extreme pressure thanks to special high performance additives. We also stock a selection of vintage green gear oils which are formulated to prevent rust and ensure the longevity of your gearbox.

Worm Steering Box Oil

This is a high viscosity, low friction mineral oil for worm steering wheels designed to lubricate and preserve the steering system, creating an easier and superior driving experience.
