Did the bug man conclude the Pennzoil oil was working best in his tests? I can't find that thread..Thanks Brian

Here is the article

Thanks.......

Pick any good quality oil and mix at the manufacturers specifications, you won't go wrong. I would stay away from the really lean mixtures though, but that is just me. more oil=more power (to a point)
Penzoil worked well as do many others

wake me when this is over ---------

**LOL**

more oil = more power, that is not true,,, you are going to have to explain that to me,, ,, and about the "stay away from the lean mixtures" how is that justified,,,,, Alot of brand name engine companies reccomend Amsoil 100:1,,, alot of the engines are flew in over 90 degreee heat half the year and no problems,,, just because a mixture is 32:1 doesn't mean that it lubs better than a 100:1,,,,, it is the molecules of synthetic oil and their technology that makes the difference,,

I believe that RTK is referring to an SAE tech paper written on some testing of motorcycle air-cooled two stroke engines a number of years ago. The research attempted to find out what various oil ratios did for power. Turned out that more oil gave more power for every ratio they tried, up to some incredibly high oil amounts. So yes, it IS true and documented in a very respected technical forum.

Personally, I'm not sure what there is to gain by scrimping on oil. It really is keeping your engine alive and trying to use the least possible seems like a very false economy to me. A little bit of clean up is a fair trade for long life and great performance, in my books.

C'mon, Dick! Wake up! There are some people that still want to beat this horse...

For one thing...more oil is going to give better compression because of better piston and ring seal in the bore and more compression...you cannot compress oil or a liquid!!!!! Capt,n

If penzoil is so great why do the makers of 2 stroke outboard engines say by using it will void there warrantys on there engines? At least they did back in the 90's things may have changed now ??
More oil more drag on the piston and ring ,the only way I can see where more oil could possible get more performance is a better ring seal for higher compression.
Synthetic oils have been proven time and time again to oil better than fossil oils,why because the molecules are all the same size,Where as fossil oils aren't and the oil itself is just slicker than reg oil.I have seen it drop the temps on just about everything it has been used in, and used in engines as a rule a power gain can be noticed, how much depends on the engine .
But 100-1 to me is pushing things a bit far, 75-1 is as low as I care to go .And so far I have not had any problems.

mmmmffph hack whazzat?
oh yeh the oil thing
bartender pour me another one - yeh 32-1 - thanks -
no dry marthingys for me thanks --

mmattockx is correct, I read it some where, AND
Others that I highly respect in the RC community have also come to this conclusion by experimentation (real experts)
I personally have done no such testing, but I can learn from what these guys have done without doing myself
Any high quality oil will be just fine. Besides, I doubt that 99.99999% of RCer's will ever wear out an engine before it gets planted and needs to be repaired anyway

Yea, Wake Up Dick and Have Some Fun

Oh, buy the way, I am giving Penzoil a try now. That way I can compare it to some other oils I have tried, and one manufacturer even recommends it too. Dicks favorite will be tried next year.

I dreamt I had an engine that I kept trying to wean from oil - just about the time I got it to run with no oil the durn thing quit.

Ahh, here we go... Found my "Dirt Rider" September 1998. There is an article by Gordon Jennings that shoots holes in many of the popular beliefs that people seem to cling to. I'm too lazy to re-type the entire article, so I did a search and found this:

I remember reading that article, many, many years ago.

While I hate removing oil from my model, I tend to stick with conservative mix ratios. This is a change from my previously favorite 100:1 position. I don't like the gumminess of the low mix ratio synthetic oils these days. But it is all based upon whim. However, I've never heard of too much oil ruining an engine.

Your ALL wrong!!

I've been running bacon grease in one my engines for 2 quarts and thus far, not a single problem. I'm convinced and nuthin' any of you so called "experts" and friends of said "experts" is going to change my mind. I just bought this engine and, while the manufacturer is Polish, I am going to to follow his every word about the oil recommendation and ratio of 5:1 in my $3592.58 motor. After all, who better than the manufacturer to know exactly what kind and ratio of oil to use in my precious engine?

BTW--this is my first gas engine and I'm more of an "expert" than any of you guys with your stupid Zenoahs and DA and ZDZ engines. Your all idiots and I'll be flying this engine for the next 50 years if I live that long.

There!! Now you can all listen to my advice and quit argueing about oil. BACON GREASE!! It puts the PIG in your engine.

I think your mixture will replace glow fuel as my favorite smell!

Read the article.....And that is EXACTLY why we run 10 oz of oil/gallon in our two stroke racing engines...

Yea gotta listen to they guys that know, Ralph knew a long time ago. Not that he is old or anything
I do like bacon too

I'm having trouble simply COOKING an adequate quantity bacon to accumulate enough grease to keep my engine running. It takes 25.6 oz of bacon grease for a gallon of fuel. My cholesterol has shot beyond 468 and when I cut my finger on an exacto knife last week, it looked like jelly oozing out of my thumb. Is that bad? [sm=tongue_smile.gif]

I always take an aspirin before I cut myself with an exacto knife. A lot less "jelly"![sm=49_49.gif]

Dick, we must drink at the same bar, next time say hi, im the grey haired grumpy one with the bicycle clips cheers ........

zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

What happened? Cat got your tongue, jongurley?
