. They plug the cleaning agent straight to the injectors and ti. The car for 15-20 mins for it to clean and voila. That's probably your safest and best bet. Other wise the additives to the fuel tank can mess or clog your fuel filter and you'll have issues with that as I am at the moment for using the Z MAX cleaners.

IIRC, the Z doesn't have an inline fuel filter, the only one is the strainer on the fuel pump. FWIW, I run the small bottle of Lucas with every tank and a bottle of SeaFoam at every oil change. I started doing this with my Malibu, (it also had no inline fuel filter) and up until I sold the Malibu, I'd get a consistent 30+ mpg on the highway out of the V6, even at 150k miles. Just my

Bumping this. Has anyone had any issues with the use of techron fuel system cleaner? At 30k miles, im wanting to use something to clean the fuel system, just in case, but am a bit worried about any long term issues, if any. Ive used fuel system cleaners in other cars without any problems, but i do ask because of what ive read regarding nissan not recommending using additives and/or cleaners of this type. Thanks guys

If you want to feel more comfortable, then keep using top-tier gas stations.

They already contain enough engine cleaning additives in their gas. For example, that Techron is basically included in Chevron gas.

Thanks felix. No chevron in PR, and the only supposedly top tier gas station that i know, i dont trust. I felt the car sort of hesitate or a lag response when using this gas, maybe a placebo/butt dyno effect. I know others with Z's in PR constantly use this gas and get mixed responses(some like it, other complain about the same lag feeling)
