Description

Castrol GTX 5W-30 C4 is a low-SAPS oil in the GTX range, intended above all for Renault diesel and petrol engines and for certain Mercedes-Benz models. It is compatible with particulate filters.

It is rated ACEA C4 and holds official Renault RN0720 and MB 226.51 approvals.

Typical figures: 12.1 mm²/s at 100 °C, 71 mm²/s at 40 °C, viscosity index 171, pour point -36 °C. The data sheet gives sulphated ash of about 0.5 %, in line with the ash limit of the C4 category.

Application

Mainly Renault diesel and petrol engines that require RN0720, and Mercedes-Benz models that call for MB 226.51.

Worth knowing

Among the Castrol oils in the catalogue, only this one carries the Renault RN0720 and MB 226.51 approvals, and it is also the only oil in the GTX range with no API class: its only class is ACEA C4. According to the overview of Renault and Dacia approvals, RN0720 was written first and foremost for dCi diesels with a particulate filter, and no newer Renault standard replaces it. According to the same overview, MB 226.51 is built on RN0720 and meant for Renault diesels with a filter fitted to Mercedes-Benz cars.

Its sibling GTX 5W-30 C3, of the same viscosity, holds Renault RN0700 and Renault RN0710, but RN0720 is not in its list, so it does not satisfy an RN0720 requirement. The data-sheet figures differ too: sulphated ash 0.5 % against 0.71 % in the C3, pour point -36 °C against -42 °C. The other oils with RN0720 are collected on the Renault RN0720 page.
