Tomoil — the whole workshop, not just the sump.
Tomoil is Sinova Group's flagship lubricant brand, blended in Germany. Engine oils for passenger cars and commercial fleets, plus the transmission, brake, coolant and EV fluids that come with them.
Where it comes from
Tomoil Lubricants GmbH is based in Stuttgart, Germany, and forms part of Sinova Group — the same manufacturer behind the Sinova Marine range we supply to shipping. Formulations use additive systems from Lubrizol, Afton Chemical, Infineum and Chevron, on base oils from ExxonMobil, Chevron and other global suppliers.
OEM approvals
Mercedes-Benz 229.51, 229.52, 229.71 and 229.72, plus Deutz DQC IV-18 LA — with certificate references.

Fluids for hybrids and EVs
Electrified drivetrains need fluids that cool as well as lubricate, and that stay electrically insulating while doing it. Tomoil's EV line covers the drivetrain, the battery pack and the braking system.
EV Transmission Fluid Type D / Type W
Dielectric cooling and lubrication for electric motors and reduction gearboxes.
EV TMF-DC / TMF-IC
Thermal management fluids for direct-immersion and indirect battery cooling.
EV Brake Fluid (DOT-5.1)
Low viscosity for regenerative braking and ABS response.
EV Grease
Low electrical conductivity for motor bearings and electrified drivetrains.
Fuel savings
According to Tomoil's independent testing, the low-viscosity series deliver measurable fuel savings against conventional grades:
up to 1.4%
Passenger car — SP/GF-6A and SP/C3 series
up to 1.2%
Heavy duty — CK-4 and CI-4/SL series
Tomoil's worked example for a heavy-duty fleet switching to 5W-30 E4/E7 gives €448 saved per vehicle per year, or €22,356 across a 50-truck fleet.
Based on these assumptions
- 120,000 km per vehicle per year
- 27 litres fuel per 100 km
- Fuel at €1.50 per litre
- 60,000 km oil drain interval
- 35 litre fill plus 8 litres top-up
- €3.24/litre lubricant price difference vs 15W-40
Figures published by Tomoil Lubricants GmbH. Actual savings depend on duty cycle, fuel price and the oil being replaced — we are happy to run the calculation against your own fleet data.
