Redline oil...new question.

[SpectraSVT]

Alright, after reading all I could in the searched posts I still have a question. I just switched from Motul 600 to Redline for one ride. I got the Redline free from a race I won. I was running Motul with 100 octane fuel @ 36:1. I ran bike dry and put in Redline ith 95 octane @ 32:1. I hopped on and went riding as usual and bike was different. I kept checking which gear I was in cause it was running better and wasn't expecting a power increase.

I have 03 YZ250 and I haven't been scared of it since the first month I got it. Yesterday it was pulling so hard I couldn't stay on the thing. I could pull a higher gear in every situation with no bogging. the change was dramatic. After reading thru the posts I found out that Redline does bad things to the brass in your carb. My question is...am I gonna have to spend $200 bux trying out 20 different oils to find something that will work as well as Redline does or was it just Motul 600? And why did it casue such a dramtic power gain? Until yesterday I thought oil was oil.

You changed the fuel and the ratio at the same time that you changed the oil, so determining the root cause of the performance improvement might be fairly tricky. There is a pretty good chance that the 95 octane fuel caused the engine to run a bit leaner, and running more oil with the 32:1 ratio will also tend to lean it a bit. Most of the MX bikes I see are running way too rich in the low/mid throttle circuits so leaning them out tends to work wonders in terms of throttle response and roll on power.

It might be worthwhile to try the same test with the original fuel, the original ratio and the Redline oil under the same weather conditions and see if you still notice a difference. Let us know what you find if you do. ;)

FWIW, it's pretty rare for an oil to change performance to any great degree.

I've run Motul with 87-100 octane at 32:1 before yesterday and never noticed any change. Only thing I can't account for would be temperature but I ran both on the same day with slight variances.

It was very strange...cause it was very dramatic. So oil doesn't typically change performance all that much? Does differing oils have varying effects with jetting?

Each oil will have it's own unique influence on the combustion process. It's been my experience that the better oils have the least effect on jetting because their cemically correct air/fuel ratio tends to be very close to the fuels we use. This is one of those areas where I'm afraid the only way to know for sure is to test it and document it.

From my personal experience Mobil MX2T, Phillips Xamax seem to have little or no effect on the jetting even when a lot (up to 9 oz/gallon) of oil is used. Yamalube 2R and Golden Spectro has a much greater influence, so adding more oil tends to lean the engine out.

I hope this helps.

THx for the info...I don't know very much about jetting and fuel mixture stuff, obviously. I'm gonna play with the jetting to see if I can get the same results with a safer premix.

spectra I use yamalube 2r on my yz 250 and was out riding one day and had to borrow some gas. I was running 40:1 pump gas and the gas I borrowed was 32:1 pump gas with yamalube. I noticed a big difference the bike ran leaner and had alot more snap.

Rich I was thinking of changing oils this year. Was just wondering what your experience was with the mobil mx2t I was leaning towards dumond tech but I have to get it shipped to me and its not cheap on the other hand my local auto parts store has the mx2t for fairly cheap.

Eric Gorr and I were doing long term testing on TiN coated pistons rings in an RM150 a couple of years ago and we used MX2T for most of the testing. I was really happy with the results we got with the oil and would highly recommend it for MX or trail use.

Okay you had to go and mention TiN coated piston rings diddent ya. Since I dont know the difference between those and regular rings you will have to answer another question.

I've been running the Redline Two-Stroke Racing Oil and no problems with carb jets (brass) here. I know everyone here don't seem to like the Redline Oil. I am not the expert everyone else here seems to be but it works fine for me. Redline uses the best base stock there is (polyol esters). I'm not sure but I don't think the cheaper MX2T uses this more expensive base stock. I also think there is lots of good oils and I am sure MX2T is also very good.

Now maybe you can enlighten me on why it costs $200 to change carb jets? Also maybe it was a something in the fuel that was hard on the carb brass.

Also anyone else having good luck with the Redline Racing Oil without there carb melting like an ice cube? Maybe try soaking a new brass jet in straight Redline Oil and Redline premix and see what happens.

BTW: several of my friends also use Redline Racing Oil, and I have no connection with Redline.

Redline Racing oil takes some time to do it's damage to the jets and engine internals. I also used Redline Racing oil with great results right up until the time the corrosion caused a very premature engine failure. Even my jets looked good for a while. Redline racing oil has issues with moisture in the fuel. Before you say that your fuel has no moisture content, think again. Moisture in the atmosphere finds it's way into fuel mixed with R R oil. It then forms black looking, non soluable globs at the bottom of the tank, not good. I track engine hours on my equipment (my aircraft background) and the net result is that R R oil reduced engine life, in particular the bottom ends, of 2 of my enignes.

I suggest using any other quality 2 stroke oil. My current fav is Mobil MX2t, I have had very good results with it.

Thanks for taking the time to inform us of your experiences Chris. I'm not so hard headed that I won't change oils if needed, and I am sure all fuels have some water in them, most a lot more then we would like. I would apprecate it if you let us know how long before you had to rebuild the bottom ends and what all was bad, lower connecting rod and pin maybe? Also does your motors see a lot of hard use like racing? I would like to know what the damage was and what all had corrosion.
I havn't had any problem with the black looking, non soluable globs that you mentioned, in fact Redline Oil stays mixed really good for me. Also I know one guy thats been running nothing but Redline Racing Oil for over 2 yrs and his tear downs have all good + everything has been really clean, even the power valve. Maybe Redline has made some changes? When was you using the Redline Oil.
You seem like an intelligent well informed person that truly had bad experences with Redline Oil, I am just trying to understand why 3 or 4 well informed ppl here has had such bad experences while others have had such good experences with it.
Again thanks for your input,

BTW: I have only been using R R Oil for about 4 months. So I am no expert on it, I just liked what I saw and heard from local ppl. Yep, now I am looking at my mix, in my tank, at my jets, no tear down here yet but I started using the oil with a freash rebuild top and bottom. So I guess unless I change oils I am a guinny pig.... LOL

my friend has been using redline in his bike for years now has never had a problem with anything.
