2 Cycle Lubricants Racers purchase racing oils for a variety of reasons. Sometimes, these reasons are not always correct. Racers many times purchase oil because it has a cool marketing name or it’s fashionable to display the logo of the brand. And in my opinion, engine builders don’t always sell oil for the right reasons. Some dealers sell oil because they make more money on it than other brands that may actually have better performance records.
At WPT, we are an engine center and we don’t sell oil for profit. We choose/recommend an oil because and only because, of how it performs in protecting and maximizing performance of your engine. And you should also know that if it goes fast but wears out your engine it will only cost you more money in replacing parts. Good racing oil is an important investment. One major way that we determine the quality of the oil is to examine the way the engine looks and measures after a season of racing. Rings, pistons, bores, bearings and wrist pins all need proper lubrication to prevent wear. Good oil also affects the sealing ability of reed valves and piston port systems. Thus, we want the engine to wear in, not wear out!
For 2 cycle premix engine, my #1 choice in oil is an off shoot of a product designed for the Military. It is called Mercury Rejuvenate oil p/n 858102Q01. This oil has tremendous lubricating abilities under very high heat loads. It is incredibly clean and will clean combustion deposits. Carbon will slowly go away yet there will be enough color on the pistons to aid in reading jetting.
More information on Mercury Rejuvenate oil p/n 858102Q01 can be found at www.rejuvenateyourengine.com (http://www.rejuvenateyourengine.com/)
My second choice for oil in an expensive racing engine is: YamaLube R. This is proven oil that can be bought around the country as well. More information on this oil can be found at the following web site:
Here are my recommendations for the mixing ratio of the oil and gas:
Powerboat racing @ 20:1 to 24:1
Snowmobile racing @ 28:1 to 32:1
We have won major racing events for two years with these products. These oils do what you engine builder wants! It will give you what you want: victory in racing!
My final works of wisdom: When you win, we do too. Please follow what your engine doctor says about racing oils.


Mercury Rejuvenate is now named, Mercury Racing 2-stroke oil

At what ratio do most of you run? I run 40 to 1 premix in my stock 2.5 200 hp. It will turn close to 7,000 rpm is 40 to 1 good?

Rejuvenate is now branded a Mercury Racing 2 stroke oil. This is what Mercury is recommending for the 300XS for the last 3 years.

I personally will run 40:1 up to 7k. 7k to 8.5k 32:1, above that 24:1. (Which I don’t ever do lol). 32:1 seems to be my happy spot that seems to yield the least amount of wear and best performance results with operating range from 7-8K on a heavier rig where motor is always working. Just my .02

Are you jetting up at 32:1 in addition.

FORBESAUTO

I jet em with 32:1 mixture. I’ve toggled back and forth experimenting with 40:1 and 32:1. Didn’t have to rejet between those 2. I would think if ya making a bigger jump than that you may to rejet a size for the extra oil

It`s interesting that this guy never mentioned anything about the different needs of a steel bore vrs nicom/chrome bore.

according to Mercury full synthetic for nicom/chrome and regular non synthetic for steel. I say this knowing full well there will be a debate to come and that's ok with me. That's how we learn.

Yet full synthetic works in omc steel bore

Probably a dumb question bud is Mercury Racing branded oil the same as Mercury Premium Plus or Quicksilver Synthtic blend? Here is the link to the Mercury Racing branded bottle https://www.mertenmarine.com/Mercury-Racing-Synthetic-Blend-2-Stroke-Oil-8M007801-1-Gallon

I started running synthetic on my steel bores before I knew better. Yet, I’ve had such good success and like zero wear issues, I decided to keep using it:eek:

Premium plus turned my red jugs an orange, but it's a good oil.
If you're at 32+ you think you're covered either way?

Can’t really answer that, but may be why my ole junk seems to live longer at 32:confused:. I ant never had a failure that I would say was directly related to lubricantion except for loosing a center main maybe. Was using a blend then and 40:1, melted a few pistons for lean and bias problems, all unrelated to lubrication. But every time was 40:1. Went to 32:1 and full synthetic and ain’t broke nuttin since. May be coincidental, but feel it gives ya that extra cushion if sumptin ain’t just right. Plus when I open em up always super clean and cross hatches still in cylinders. I figured if ain’t broke, don’t fix it.

Same here. Never run a Merc much yet but T see dubya three has always been my targeted favorite and bought on price, lowest is the bestest. I've run every brand you can think of in my old crossflow, scream that baby over 6k every time out completely stock and never had an issue with it mechanically. Lower units on the other hand? Only ever run the merc fluid, even in my Rude since new its been Merc fluid from day one

I have always had great results with full syn. lube in all my machines. From lawn mowers to my fleet of work trucks.....outboards to weed wackers.
I also use it in all my air compressors and one is 35 yrs old and still works fine.

A PAO-based synthetic basically looks like a mineral lube with only the most desirable molecules left.

Ester-based synthetics can in theory be more customized and more exotic.

Powerboat racing @ 20:1 to 24:1


A very successful Swedish offshore racing team back in the nineties many years later claimed that they believed that one reason for their success was that they discovered that the engine was running stronger with a very high oil ratio like that.

And I thought Mercury oil was a rip-off:

Do ya`ll remember those old 1940, 50 and early 1960`s outboards. They ran 25-1 and never blew up.

I have always ran at least 32 to 1 in my premixes...
25 to 1 over 6500 rpm
