"premix" additives in oil

[dajohnson53]

If I wanted to more or less constantly add de-carb and stabilizer to my fuel, could I just add it to the TCW3 oil? I premix and keep a supply of oil on the boat to measure and add whenever I fill the built-in tanks. By doing this, the fill up procedure would be quite a bit cleaner and simpler - I'd just add the prescribed amount of oil, and the stabilizer and de-carb would be there, rather than messing with three different containers, three different measurements. I guess the question is, is there any harm to the oil or the additives to store it mixed in with the oil? It could theoretically be in there for 6+ months if I have unused oil from one season to the next.<br /><br />Related question: I've heard that Seafoam brand de-carb treatment is also a fuel stabilizer. Does it really stabilize fuel as well as, for example, Sta-Bil?

Irrespective of what other problems that might cause you would have to recalculate your oil/gas mix as it would no longer be 50:1 since you will have added to the volume of oil by adding the "additive". Sounds like you would be making a complex and messy situation worse.

Wow, even though I have an oil additive that I add to my oil as you are mentioning, I would reccomend against what you are thinking of doing.<br /><br />As to the additive I am testing, (There is no way I would recommend it to anyone else), I cant say, But if its good for racers, its good for Bassers.

Don't do it.<br /><br />And what do you mean by ""I premix and keep a supply of oil on the boat to measure and add whenever I fill the built-in tanks.""<br /><br />What are you currently premixing it with?

Re: "premix" additives in oil

I'm not worried about getting the oil-fuel ratio right - I can handle that. I'm wondering if it would harm the additives or oil to do this ahead of time, where it would maybe sit for (in most cases) a week or so, in extreme cases for 6 months. In other words if anyone knows if there is a chemistry-related reason not to do it. As far as mess and hassle go, I'd rather do the measuring at home, in large batches, rather than in the boat in small batches as I add 5 - 25 gallons of gas. To me that would be easier and less messy. Thanks for any advice you can give.

Added to the fuel-OK, added to the oil-NO.

By premix I mean I mix oil and gas in the tank rather than oil injection. I keep a jug of oil on the boat and everytime I put fuel in the tanks I put the correct amount of oil in with it. <br /><br />I'm currently using Castrol TCW3, and generally use it, or one of: OMC, Quicksilver or Pennzoil, depending on what's convenient when I run out.<br /><br />Based on the comments I've received so far, it sounds like my idea is a bad one. Still uncertain why though. Thanks for the advice!

Re: "premix" additives in oil

D, my point was that if you had been putting 1/2 quart of oil in 6 gallons of gas you will have to recalculate a new ratio because a 1/2 quart of your modified TCW3 will have less than 1/2 quart of oil in it. The difference being the volume of "additive" you have added. Lets say you add 16 oz of "additive" to a gallon of TCW3 oil which would normally mix with 50 gallons of gas. Now a 1/2 quart of "modified lubricant" will mix with 44.4 gallons to make a 50:1 ratio. You better keep a chart on board the boat when you fill up.

Yes, I understood that - and as I said, really I can handle the adjusted ratio . I was just wondering if chemically, it was OK or not. I've gotten pretty unanimous advice that it's a no-go, but am still curious why. Thanks for your advice.

I believe the additive may not mix w/ the oil. It is gas soluable. You may wind up getting no oil and all additive for a short period of time. I wouldn't think it was worth the chance! IMHO Good Luck, Joe

Ah, that certainly makes sense. For you-know-what's-and-grins, I might give it a try in a jar. Just curious mind you and making general conversation. Should be boating, but instead I'm asking esoteric questions about mixing additives and spark plug minutia.
