When the product is added to the old depleted oil it immediately neutralises acid which has built up in the crankcase and adds lubricity, enabling the detergents to safely dissolve contamination which has built up in the crank case, on piston rings, in the variable valve timing and in the hydraulic valve lifters.
These harmful contaminants are held in suspension and safely removed with the old oil. On completion of the cleaning process the reduced amount of depleted oil left in the engine is acid neutral ensuring the new oil stays cleaner for longer.
DIRECTIONS FOR USE:
Add one 400ml bottle of Tec4 Oil System Cleaner to the crankcase of a typical motor vehicle prior to changing the oil. Idle the engine for 10 – 15 minutes.
For engines that have not had the oil system regularly cleaned idle for 20 – 30 minutes.
On completion carry out the normal oil and filter change procedure. For larger capacity engines add at 10% by volume to the oil.
