2 stroke oil in your trucks?

[waxworkz]

ok so i did a lot of reading in the LS1 forum about the adding 1oz of 2 stroke motor oil per 5 gallons of gas. i finally took the plunge and did it! i didnt see a thread on here about it so i wanted to see if any one else has done this and the results?

i have, in one tank, felt a better idle, easier start, and what i can only describe as a "less pedal to move" feeling. i havent had a chance to do a second and third tank to get MPG increases so i'll wait and up date after i go through some tanks

I put my old 2 stroke mixed gas in my '75 K-5 and it smells like a banshee!! Other than that, I haven't seen any benefit from it, not saying that there isn't though!!

well this is marine 2 stroke oil, not just old lawn mower 2 stroke. i have been driving it for 2 days and i dont smell any thing dfferent. i did notice right away that the truck starts way easier! it used to take the engine turning over twice and now it only turns once

The stuff I'm talking about that i use is full synthetic race 2 stroke oil used in quads and it has a very noticable smell, I love it!

I too have just started this, just put in like 2 days ago though. But the amounts we are talking here are like a 500:1 ratio vs regular two stroke oil gas mix of something like 40:1. The purpose is to cleanse and lubricate the top end and entire fuel system. I read that whole 43 page write up on ls1 forum and have been more than convinced. Im not expecting a mileage increase on this first tank however, but thats because I have known bad O2 sensors and want to burn the craip off first and then replace the sensors.

Thought I would repost this. If you do a search on seafoam you will find that this has been discussed. I too read all of the pages and felt it was worth trying. Make sure you are using the correct "rated" 2 stroke.


I thought about it for a month or so and decided to take the leap of faith. I did it for 3 tanks because according to the OP it said you would need to do it for at least 3 tanks of gas. I bought a 12oz bottle of 2 cycle TC-W3 rated at walmart and used the right ratio which turned out to be 4oz every time i filled up. I got 13.3 on the tank before I started the 2 cycle treatment. 1st tank with 2 cycle was 13.5, 2nd 14.2, 3rd 14.8. As you can see the tank #2 got just a little under mile better, tank #3 got 1.5 miles better. I didn't change my driving habits, and went further on a tank with this treatment.

I was looking for better MPG/smoother idle and not so much more throttle response and I am happy with the results. I am going to start using it again on my next tank when I buy more. You will see that the MPG stays constant and not get better with more use, after 3 tanks or so it will just keep things cleaner longer from what I've read.

I had to get it inspected shortly after my last tank with this treatment and it passed with no emmissions problems as a result from using it.

Results with most likely vary but I was pleased with it.

I've been doing this for a whille. You can mix it as lean as 1oz per 5 gallons or as rich as 1oz per 4 gallons. Technically 1oz per 4 gallons is a 500:1 ratio...1oz per 5 is lean. Don't go richer or leaner than those numbers...

I've gotten better mileage & a quieter fuel pump out of my Tahoe. I just changed the plugs too & they barely looked used. I run this in my 94 k2500 too & I got a 2-2.5mph increase and much smoother running.

It's a worthwhile additive for the gas we have now.

I was doing this in my 98 Tahoe and I didn't notice any difference in mileage or idle (My idle was perfect with the GM Injector upgrade anyway)

I had forgotten about doing on my 04 to see if it makes any difference. Especially like someone else said about the crap Ethanol gas we have to use now.

yeah i was doing the math and 1oz to 5 gallons isnt 500:1 its more like 640:1 but at 1oz to 4 gallons it is 512:1

i too have just started doing this, make sure its a tcw3 rated oil and mix correct and seems to be making a difference.

Thanks for posting that...I forgot where it was...lol...

Ill start this as soon as I get to wally world. thanks!

Just started doing this 2 days ago, but I only had 1/2 a tank at the time. I'm gonna fill it to Full today or tomorrow and add more oil. I've been having a "stutter" at idle that 2 cleanings of the TB havent seemed to touch so I'm hoping this will clean the plugs and things and help eliminate.

I'll post more when I know more

 

[Physh1]

Just make sure you give it 3-4 tanks before you make a decision to continue or discontinue use. It will easily take a few tanks for the effects to kick in & mileage to increase...it's not an instant result!

this is a really good long term gas additive that works, and alot cheaper, but if your counting on it to clean the plugs to cure a stumble (which it will over time) i would suggest replacig the plugs and wires now and the 2stroke oil additive will help keep them clean from there on

@swathdiver Do you run the tcw3 with the E85? About how much to a full tank?Gonna be filling up from half on my second tank of E85. First time putting E85 in was also from half of regular 10% 87.

I'm VERY curious about the reality of this vs the hype. And here is why....
Motor oil....a VERY reputable machinist was helping my buddy and I rebuild his LS engine recently, and for break in oil he recommended X...but more importantly he spoke about oils in general with modern engines. Explained how you really shouldn't use any kind of conventional oil in modern engines because they are too dirty, and it translates down the road to plugged up cats. Irrelevant to this post, but the two stories clicked as one with me as you are putting extra oil/pollutants into the fuel, which will also end up in the cats.
Just my thoughts, I don't know....I know that with the 2 stroke system you want the extra additives....but with a 4 stroke....I don't know. I see long term failure, or problems. Carbon build up, or other garbage.

I just had to reply, even if I'm barely a believer in it. But... I gotta say been using Mystic 2 stroke Synthetic for 20+ years in Saws, motorcycles, outboards, weedwhackers and as a Diesel additive on older diesel engines Mainly to protect the Injection pump from low sulfur fuel. When my two gallon can of 32/1 mix gets old- 60-90 days, guess where that gas goes. My experience with 2 strokes is This oil is the best and cheap too. High output engines, no ring sticking and clean inside. Diesel pump experience is A few hundred thousand miles, no failures at around 100-150/1. Inside of the 2 stroke engines are very nice, bearings wearing extremely well, combustion chambers and exhaust ports no carbon buildup, only an occaisional light cleaning of the exhaust screen. (small amount of ash. )Thats why it's not TCW2/3. But it is JASO FD, which is a way higher standard, and nearly smokeless. Not too many Oils meet JASO FD, Most are repackaged Mystic.
