Description

Liqui Moly Special Tec T3400 15W-40 is a semi-synthetic year-round oil for petrol, diesel and hybrid vehicles, both naturally aspirated and turbocharged.

The oil carries ACEA A3/B4, ACEA E7 and API CI-4/SL. It holds no carmaker approvals, and the manufacturer gives no recommendations for specific makes.

Typical figures: 15 mm²/s at 100 °C, viscosity index 135, HTHS at least 3.7 mPa·s, NOACK 8.0 %, pour point -36 °C. Available in 1, 4 and 205 litre packs.

Sulphated ash is 1.5 %, so this is not a low-SAPS oil: it is not intended for engines that require particulate-filter-compatible classes.

Application

Petrol, diesel and hybrid vehicles, naturally aspirated or turbocharged, for which a full-SAPS oil to ACEA A3/B4 or E7, or API CI-4, is suitable.

Worth knowing

The “pour point -36 °C” line does not tell you how low a temperature this 15W-40 will still start at. The 15W grade in the data sheet is confirmed by two other tests: CCS no more than 7000 mPa·s at -20 °C and MRV no more than 60000 mPa·s at -25 °C; for T3800 10W-40 the same limits apply at -25 and -30 °C. Why the pour point is misleading and what CCS and MRV measure is explained in the article on the oil data sheet.

With Touring High Tech 15W-40 it shares the SAE grade, ACEA A3/B4 and API SL. Beyond that the lists diverge: T3400 adds ACEA E7 and API CI-4 but has no equipment manufacturer codes at all, whereas Touring High Tech has ACEA E2 and API CG-4, Allison C-4 and Volvo VDS approvals and compliance with, among others, MB 228.3, MB 229.1, MAN M 3275-1 and Mack EO-L. If your documentation requires one of those codes, that is the can to go for. T3800 10W-40, by contrast, has ACEA E9, API CK-4 and API SP but no ACEA A3/B4, and its sulphated ash is 0.9 % against 1.5 % here, NOACK 13.0 % against 8.0 %.
