Description
Elf HTX Prestige 40 is a mineral monograde SAE 40 oil from the HTX range for cars from roughly the first half of the 20th century. It also suits engines without an oil filter or with a centrifugal cleaner.
The oil is rated API SL and CF; the data sheet gives no carmaker approvals.
Its detergency is deliberately moderate, so it does not wash away the carbon deposits that act as a seal in such engines. It also protects against rust during long periods of storage. Typical figures: 13.8 mm²/s at 100 °C, viscosity index 135, pour point -24 °C. Available in 5 litre packs.
Application
Veteran and vintage cars from roughly the first half of the 20th century, including engines without an oil filter or with a centrifugal oil cleaner.
Worth knowing
With no W in the designation, only the hot viscosity is specified for this oil. The SAE viscosity value table gives grade 40 a range from 12.5 to below 16.3 mm²/s at 100 °C, and the 13.8 mm²/s from the data sheet lies inside it, while for a monograde the table sets no cold cranking or pumpability limits. The pour point of -24 °C is the highest in the HTX range: it is -27 °C for the two 20W-50 oils and -36 °C for Generation and Chrono.
Among its properties the data sheet names dispersant additives that keep soot, wear products and combustion products from settling in the crankcase and on engine parts. Elf describes the mineral base as designed for ordinary driving conditions, and for modified engines that see track use the range has the synthetic Chrono 10W-60; all five oils are collected on the Elf HTX range page.
