Of course the synthetics have about twice the viscosity as group 2 mineral oil at upper cylinder temps and so you have to add twice as much group 2 oil to the gas than what you'd add with synthetics. I use Synplus on my air cooled street bike at 27/1.

If any of you think this is crazy, using a pure mineral oil in a dirt bike, please consider that many people have successfully used Yamalube 2R in motocross bikes and it's only around 67% group 2 oil and 29% group 1 oil. It has no synthetic in it. Also Golden Spectro is a classic old time racing oil and its mostly group 2 oil with a little group 1 oil in it. It has no synthetic in it. I'm afraid that once again we've been the victims of oil manufacturer propaganda and general rider misconceptions that are shared amongst riders.

Of course rich jetting greatly contributes to spooge, but if you're using an oil with synthetic but you don't have any spooge then either 1) your silencer is catching it all, 2) your jetting is too lean. Some spooge is normal, I just don't want the excess amount that synthetics cause. My engine is air cooled which gets hotter than water cooled but using Synplus gives me long engine life. It's all about the NGK heat range. That indicates how hot the engine is getting. If you're not sure about your heat range then just look at the color change line on the ground electrode. It should happen halfway along the electrode. Closer to the end means the heat range number is too high, and closer to the threads means the heat range number is too low.

About a year ago I went through your data on 2 stroke oil. I changed from echo powerblend gold at 40/1 to formula k2 at 40/1 on my chainsaws, brushcutters/weedeaters. I expected some splooge out the exhaust. I haven't got any. All my equipment runs heat range 7 sparkplugs. I run regular unleaded 85/15 87 octane gas.

@@kraftzion most probably it is settling in the silencer/muffler. You should take the pipe off and flush it out with gasoline. Or maybe your engines are jetted for non-ethanol gasoline but you are now using gasoline with ethanol which is making the jetting lean. see www.dragonfly75.com/moto/no-alcohol.html

I have spent a bunch of time in your web site - just a massive amount of interesting information I was wondering for KTM TPI bikes if you would just stick to the recommended motorex cross power 2 or use something else that’s easy to purchase? Again thank you for all the great information

I don't like Motorex because of all the group one oil that they put in each product. here's my rules for optimal engine oil selection 1. use synthetic or group 2 oil (or combination) if the CDI doesn't adjust the timing by the engine load. 2. Avoid oils with over 20% Group 1 oil. 3. Avoid oils with a high level of viscosity modifier. 4. avoid FD rated oils for engines using a number 9 or 10 spark plug. 5. use an oil with over 50% synthetic and or castor if the engine uses a number 9 or 10 spark plug. 6. If you rarely take apart the engine to clean the power valves then avoid all oils with any group 1 oil. 7. for engines with a number 7 or 8 spark plug use mostly synthetic oil if you want clean power valves, less carbon on the head/piston/pipe, less exhaust smoke, and don't mind spooge. And if avoiding spooge is high on your priority list then use a fully group 2 oil.
