SIGNIFICANTLY ENHANCED PROTECTION FROM WEAR AT START UP*

The vast majority of engine wear happens at start-up. Ensuring effective protection at this stage is therefore essential. 

FILTRON oil filters are tested and proven to protect under pressure

• The anti-drainback valve prevents the engine starting ‘dry’ and unprotected by retaining oil in filters that are mounted to the side or upside down
• This means oil can circulate rapidly, reducing the risk of wear and engine failure
• In laboratory tests, the anti-drainback valve in our filter was proven to retain oil better, losing 84% less over a 12-hour period than an equivalent competitor *.

_{* Controlled M+H laboratory test of FILTRON OP 616/3 vs equivalent product from a competitor manufacturer. Anti-drainback valve efficacy test proved FILTRON OP 616/3 lost 84% less oil over a 12-hour test period.​}

INCREASED PROTECTION AGAINST ‘DRY’ ENGINE STARTS

The anti-drainback valve retains oil inside the filter housing, ready to lubricate the engine from the moment it starts.
