Default Mixing gas additives ?

Are there any issues mixing gas additives in the gas ?

I have been adding Star-Tron to gas, all during the season...

I'm having the motor winterized by Marina, and I believe they use Sta-Bil blue.

Are there any issues having two different additives in the gas ?

Thanks !

I'm not an expert but I have not had a problem as of yet. I also use Star - tron. I have been buying all my gas on the water the past couple years which already has an additive in it.

I use Star-Tron also, all year with every fill up.

I remember seeing a note from them that it is compatible with other additives, but I can't find a 'FAQ' on their new website.
http://www.starbrite.com/startron

But there is a left over FAQ on their old web site here:

Star tron is compatible to any kind of additives you have used previously without any danger.

Unfortunately this is not true everywhere. For instance, MVYC does not add additive, they do sell the bottles though.

I would recommend getting the ValvTect gas whenever possible. There are a bunch of marinas on the Lake that carry it. In addition to the additives they test the storage tanks periodically as well.

Correct, Fays does not add stabilizer either or at least when I asked this spring they confirmed they did not.

I've been using both Star-Tron and Sta-Bil Blue (Marine) together for years and have never had a problem.

I was advised by a marina service manager to use both as they do a better job together than individually.

Interesting. I thought all the marinas used the valve tech now. Glad to know they don't so I keep my eye out though I really always use Lanes End and trexlers

So, being a big fan of Startron and always filling the toon with Valvetect, do I need to add anything to my tank for storage or is the Valvetect adequate?
This is new territory for me as I haven't had a boat for over 30 years...
I suppose dumping a bottle of Startron in wouldn't hurt...

Startron also is a stabilizer. I thrown in the recommended amount for offseason storage as described on the label when I fill up for the last time and let it run to get it thru carbs.

I don't use stabilizer during the season....only when I put everything away.
I add Startron to the jet ski's and run them for a few minutes before storage.
Don't do any other maintenance other than hooking up trickle chargers because they are stored in a heated garage.
I try to run the gas down in the fall so I can start with a fresh tank in the spring.
'So far,it's worked well.

The ValvTect website says their gas is good for a year. I have a Yamaha outboard and still put their conditioner/stabilizing when I add gas. Probably not necessary but for a few extra bucks it makes me feel better.

I have a Yamaha 150 too...I will add some Startron after the last outing on Columbus Day. Between that and the Valvetect it should be fine til Spring.

Ambrose Cove adds Startron, but I still add Stabil. Never had a problem.
