The GMMG Registry Forum

As everyone knows I snowmobile about 3 months every winter at our lodge near Jackson Hole & Yellowstone. Let me know if you ever want to ride in Wyoming.



I was reading my latest SnoWest and there were some tips about gas from Dustin Pancheri @ Starting Line Products......



'Fuel can loose as much as 3-4 octane per month - that's one octane point per week. Keep fuel fresh. Look for busy service stations to buy your fuel.'



Snowmobiles need Premium with no ethanol.



That got me thinking about our GMMG's........ Maybe the 'experts' will give us some tips?



What do you do when you store your cars?



Do you use a fuel stabilizer? What & how much?



What do you do for storage over the winter? How do you prep your car?



Here's what I do (not saying it's right) but what I do.........



I use Stabil or Sea Foam in the gas every fall & always add a little (not much) red ISO Heat just incase there is moisture.



All cars are started for a few minutes at least once over the winter.



The gas tank used to be full but not anymore with the short fuel life. Now I try & keep it around 1/4 so I can add a little fresh gas in the summer.



Over 20 Battery Tenders plugged in for anything that is not started every week or so. (Snowmobiles, ATV's, lawn Mower, boats & all cars)



I'm hoping Aaron (BB #34) will share how he hard wired his Battery Tender.



Oil is changed every 2 years for the cars I don't start or drive all the time. Once a year for the drivers that I put less than 3k miles on.



Matt Murphy & I talked a lot about oil & he was very insistent.......



Only Mobil 1 5W20 & never-never use a K&N filter. When I wanted to talk about K&N & was insistent that I use a paper filter. I don't know why but that was his opinion.



JD & I talked about oil filters - Only Mobil 1. JD...... Would you please share what you told me?



Cars are washed & clean - I use painters plastic because it does not scratch like a car cover. If a car cover goes on there is plastic under it.







This is what I do. What do you do?

I used to worry about flat spotting tires until a Goodyear Tech guy clued me in.



He said that was once a problem but only with old bias ply tires. Modern radials don't have that problem, at least the Goodyears don't. I've never had any problems with the F1s on my Earnhardt car.

The F1s on my HOSS flat spotted on me about six months ago. The car had been sitting for 6 months, maybe longer, and since I hadn't felt anything like that in a few years it shocked the crap out of me at first. Took a good six or eight miles to smooth out. These tires only have 1,100 miles on them so the deep tread depth does add a little to the flat spotting.
