Finally we have some signs of spring in northern Ohio after lots of rain to wash away most of the winter road salt. So yesterday I got the baby cars uncovered and on the road again. Xfire Limited Coupe started and ran great after the winter break. Did a 100 mile road trip. Much fun after a winter of driving a big 4X4 SUV. The other baby car that gets a winter break is my old 1990 Nissan Z two seat coupe (NA) which will turn twenty this year. It also started right up however the engine ran a little rough and idled poorly and had some vibration that I did not have last fall. I did a 100 mile trip and topped off the gas but still had the same problems. I added a pint of Seafoam (from Autozone) to the gas tank. After the Seafoam add and about 10 miles of driving all my problems disappeared and the old Z is running and idlling better than ever. Quite a few Z people (both turbo and NA) use Seafoam in gas tank, crankcase and throttle bodies for maintennance. Does anyone have any experience or comments on Seafoam for our Crossfires?

 

Some add seafoam to gas , I use Stabil. I add to the last gas of the driving season, and run the stored vehicles every two to three weeks during winter. I do this, to try and avoid issues in the spring.
I have heard others say they have luck with seafoam to clean injectors after they get gummed up.

 

Seafaom is like gold over on the Jeep forums I am on. I have often wondered if anyone used it here. I normally just use it in our Jeeps every now and then in the gas.

 

My boat dealer recommended a combination of Seafoam and stabilizer for winter storage. I've been doing so with snow blower, tractor, boat, and this winter in my new 07XF .

 

I've been using a bottle of seafoam in the gas for many, many years with excellent results and I highly recommend it. I use it at every oil change which is about twice a year. It does really clean up everything.
