DrewzVR6 2 Posted February 7, 2015 Report Share Posted February 7, 2015 I was going to have my engine Terracleaned then came across the in line fuel cat which is supposed to updgrade the octane thus cleaning the fuel system. Now as i have limited tools and experience do i have to depressurise the fuel system to fit this in line fuel cat? i have a haynes manual but it doesnt cover the vr6 engine.

VR6Pete 1,455 Posted February 8, 2015 Report Share Posted February 8, 2015 Save your money mate. Those in line fuel cats do nothing. You will see benefit from running some redex and basic serving as opposed to terracleaning. I'm still a bit sceptical about that as I've not seen any proven benefits.

Mk3highline 287 Posted February 8, 2015 Report Share Posted February 8, 2015 Or use chevron tecron I've used a few times and it's gave best results from rest of the stuff available I used to work in a parts shop so tried them Or forte gas treatment is also good VR6Pete 1 Link to post Share on other sites
