2-cycle oil as a fuel add in 4-cycle engine

I can't speak for 2 cycle oil, but I have an Inverse Oiler on an 88 E-150 van for close to 20 years. It has never run dry so MMO has been fed to this van for almost 20 years. Each year its on the NYS Emmissions machine and passes with flying colors. I have never replaced the cat converter.

I forgot to mention, a few weeks ago my Jeep passed the emissions test no problem with about 300:1 in the tank. :)

Hey folks, tried the 2-cycle oil in my last four tanks. Used a 500:1 gas/oil mixture using the full synthetic Pennzoil TCW3 oil.

Two of those tanks were highways trips were I was following someone else and driving very, very fast. I saw about 18.6 MPG out of these two tanks, which is pretty good as we were doing about 85 MPG. I don't usually drive 85 MPG, so I can't really say if there was an improvement or not. I will note that when I'm on the highway at my more-usual 70 MPH, I struggle to hit 18 MPG.

Two of the tanks were bank-n-forth as usual to work, where my speed is carefully controlled. (Most of it is on a military installation where speeding is highly discouraged.) I saw about 0.5 MPG increase over my normal mileage.

At the end of the current tank, I'm going to try Lucas UCL and see what happens...

thanks,
ben
 
Over the years I've used a variety of TC-W3 oils at about 400:1 in some of my vehicles that had mega miles on them.

We have run our vehicles thru many EPA inspections with no issues. However, I do skip pre-mixing a tank and run a fuel additive treatment thru before hitting the sniffer. If that makes any difference I'm unsure.

I've never seen a big fuel mileage change. However, I never tracked it that close but will be soon in my 07 Cobalt. This will be a good car to try and see if anything can be done in regards to mileage as it gets run over the same course very day. The mileage the wife gets is very consistent as well. After a couple months of playing, while not telling her what I'm doing, we'll see if there's a seen difference on the DIC.

Also, in some cases the fuel pumps are quieter when using the mix.
 
I've used SuperTech TC-W3 in my LeSabre for a few tanks now, and initial results are encouraging. The dose is somewhere between 500:1 and 700:1. Not terribly precise, I know.
 
I use TWC at a 500:1 in my direct injection gasoline engine in hopes it helps long term reliability. I see little or no value with a standard fuel injected setup.
 
The car seems smoother and not as noisy. And it may be helping mileage. I'll do further investigating with it. And with SuperTech TC-W3 available at $1.64+tax per pint, it's cheap enough per tank to try.

C'mon statistical significance!
 
Anybody with actual mpg numbers where it helped? I put 4.5oz or so of Pennzoil TC-W3 semi-synthetic (marine) in the Ranger. Defiantly a difference but I can't tell what it is. The wife drives it so I don't think I'll be able to get any mpg points. When I drive the Ranger I can get 31.. I just filled it up after she drove it and got 29.8.

What does everybody use to measure?? AAP had nothing so I guess I'll have to check Wal-Mart.
 
Found the perfect measuring device. Breast milk bottles.. had some left over. Not only does it measure you can pre-measure and leave the big bottle at home. The ones I have only allow 2.5oz though so for the bigger vehicles I'll either have to pre-fill two or bring the big bottles.
 
Alright I'm game for experimenting with some 2 cycle oil in my Jeep.

If you had to choose between the various 2 cycle oils that amsoil produces to run as a test which one would you pick and why? The reason I ask this is because I have gallons and quarts of various Amsoil 2 cycle oil sitting in inventory getting old and the Jeep has an unquenchable thirst for gasoline. I look forward to your various replies. Also, does anyone have + or - comments on prolonged 2 cycle use from UOA history?? I'm running SSO in my Jeep right now, and just want to make sure that the 2 cycle doesn't disturb the amber goodness that bathes my crank shaft!

Sabre Pro. No sense in using the more expensive stuff.

I usually go off of the markings on the side of the bottle. It's worked pretty well for me.

My Buick is idling like it's on Prozac. Really steady, in other words. It used to wander a slight bit without the 2-cycle oil in the gas. No word on mileage yet, as I'm still going through the tank I was on in my previous post.
 
I've put about 75-100 miles since adding 2 cycle to the Aspire. It had 3/4 tank when I added but when I filled up it I added 4oz of MMO. Since adding the 2 cycle "sciphi" I agree with you on the idle. Steady and much quieter.. unfortunately I can hear every other loose bearing on the engine. Seems I can shift at lower rpms without lugging also, one thing I noticed on the Ranger to. Unless I run out or have problems I'll be adding some at every tank.

There's likely some benefit, and some tradeoff to dosing our gas with stuff besides gas. One is getting weird looks at gas stations.

Something I noticed was that the bottle of oil was cool in my hand when the rest of the contents were scorching hot after baking in the afternoon sun. Maybe it's reducing fuel system temperatures a little bit, improving resistance to pre-detonation of 87 octane. Or maybe I'm making my ignorance here more obvious. Likely the latter.

Well, adding oil to your fuel system without a doubt is a good thing. Whether it increases MPG or not is questionable, and I don't believe a single person that says "I got 1mpg more" or anything like that...they just don't have the scientific equipment to accurately test MPG.

It does, however, stand to reason that adding more lube and creating a better ring seal with the oil, should, theoretically increase your gas mileage...slightly. Nobody here has the equipment to actually measure it.

It doesn't take equipment to accurately measure it. All it takes is trending data.

With that said, I don't think I saw an increase. My MPG pretty much stayed the same, but I'm still using it.
