We are talking about fuel, rather than oil additives. But as far as oil additives goes, I add Lucas Synthetic @ 20%.

 

I know I'm old and really stubborn but WOW.

I have never been a supporter or user of additives of any kind. I never put anything in my crankcase but conventional motor oil. I never put anything in my differentials or transmissions but conventional gear oil. I never put anything in my radiator but green antifreeze. I never put anything in my tires except air.

A lot of people told me I was just being stubborn but their equipment wasn't lasting any longer then mine. I guess this helps me understand why. I wish I could say I was that smart but the truth is, I couldn't see spending extra money on something that didn't have a clear return on the investment.

Even in my cars I do the same. Valvoline 5w-30 in both the wife's PT Cruiser (197,000 mile) and my Dakota (142,000). I also put cooler thermostats in both of them right after we bought them. I have always thought that the 195 degree t-stats were too hot to get serious miles out of a gas engine. They both run at 180 degrees.

I'm guess I'm just and old school, old fart.

 

I use Lucas in my fuel everyother fill-up (so twice a month)

Always add Lucas every oil change.

I'm a little over a million miles on my 74 Pete's rebuilt BIG 3 and still doesn't burn (or leak) a drop...... injectors/pump are the same, never been changed.

 

one can tell YOU have never been stoped and had them check your fuel.....? i have been and they DON'T do any "chemical analysis" all they do is stick a tube in your fuel tank and pull up some, if it has a red tint to it you get the ticket.... they don't ask or care what you added, if it's red it's farm fuel and you get a ticket

3 or 4 times a year they do it in the town i live in. they just stop EVERY car truck or semi going thrught town

 

I'm not sure about your state, but here in Indiana, they do a "dip test" with a stick and see if there is red dye. If there is, then you get a citation. On the citation, you have to sign. If you refuse to sign, then there is a spot for your comment and the officers give it to you anyways and you have to go to court. Not sure what you could do to fight it really at that point anyways, but it's an option LOL

 

Probably similar to a pH test strip; the stick reacts with the chemical in the red dye, and turns an odd color. If it is just red transmission fluid, no such reaction occurs.

BTW: In the five years I've been an O/O, and a combined total of maybe a year on the road before that since 1991, I've NEVER had my fuel tested. Not even once. :thumbsup:

 

Yeah, they put it on a wooden stick and dip it (my little brother is a MCI here in Indiana)

I have only been checked 1 time and that was in Montana back in '02

 

Iuse lucas fuel treatment every 10,000 miles when I sevice my truck. fill the primary filter with it & the rest goes in the tanks. always saw a m.p.g. increase when using.

 

Then why not use it every tankful? (in smaller doses, of course).

 

It's my understanding that there are bacteria that can (and, I guess, do) grow in the bio-fuel. In states like IL, MN, and IA, you can find bacteriacide for sale as a fuel additive. I've had to change my fuel filter a couple of times after fueling in IL and MN. I did try that additive a couple of times when I fueled there and the filter did last longer, so there may be something to that. With company trucks, you simply call the shop and ask then where they want you to have the filter changed.
