Description

Liqui Moly Special Tec T3800 10W-40 is a semi-synthetic year-round oil for petrol, diesel and hybrid vehicles, both naturally aspirated and turbocharged. It combines a passenger-car class with heavy-duty diesel classes.

The oil carries ACEA E7/E9 and API CK-4/SP. It holds no carmaker approvals, and the manufacturer gives no recommendations for specific makes.

Typical figures: 14.1 mm²/s at 100 °C, viscosity index 150, HTHS at least 3.7 mPa·s, sulphated ash 0.9 %, NOACK 13.0 %, pour point -39 °C. Pack sizes from 1 to 205 litres, including 3.5 and 4 litre cans.

Application

Petrol, diesel and hybrid vehicles, naturally aspirated or turbocharged, where an oil combining the API SP passenger-car class with the ACEA E7/E9 and API CK-4 diesel classes is suitable.

Worth knowing

The heavy-duty ACEA classes E7 and E9 and API CK-4 sit here alongside the petrol class API SP, and the passenger-car ACEA A3/B4 is not in the list. That is what sets this can apart from Leichtlauf 10W-40, which has the same viscosity. The only code they share is API SP; Leichtlauf adds ACEA A3/B4, official MB 229.3, VW 501.01 and VW 505.00 approvals, and compliance with MB 229.1, PSA B71 2294, Renault RN0700 and Renault RN0710. T3800 has none of these codes, so wherever the service book names one, an identical SAE grade settles nothing.

The figures differ too: NOACK 13.0 % against 11.0 %, base number 9 against 11 mg KOH/g. Sulphated ash of 0.9 % (1.0-1.6 % in Leichtlauf) is no substitute for an ACEA C-series class: this oil’s list has none. For heavy-duty diesels, the article on which ACEA classes remain and which are new explains that E9 gave way to E8 and E11, and that E7 is meant for older engines and is not recommended by ACEA for Euro VI engines. This oil has neither E8 nor E11.
