While going through the obbball accessories that were supplied with my engine and that the dealer left on the boat there was a blue tag informing that the motor had been programmed to run 100-1 oil from the factory.
I am quite sure the dealer mentioned it was 50-1 and he even bought some regular two cycle oil so we would be sure to have enough. Why would he reprogramm the factory settings? Is it better to run this engine 50-1?
I have always suspected that maybe the 100-1 was just a ruse to get around the EPA.
I did give the dealer a call but on the weekends I would not expect a quick answer.

Ixniegh.

I use the 100. Yes, it's more expensive, but my understanding is you use less. You can go 2+ seasons without having to refill after "breakin". It was either that or I just did so much more motorng during first season. Lets put it like this, I finally finished my second gallon since 06'

Just make sure your computer & oil match. Don't get cheap after investing in the E-tec. Feed it right

100: 1 is less oil than 50:1 right?

In the old days, we would run 'double oil' for the 1st tank as a break in...

w/ DFI I have no idea...

personally, I'd call caribe' marine in the keys... (Tavernier) they know their stuff...

or, are you saying use the synthetic 100:1 2 strroke oil, like amsoil makes?

Hi Guys
Just put an Etec 90 on the back of our M and the dealer set the computer to use more oil in the run in period when it has done the time it will revert back to normal oil usage
Cheers

E-tec pushes their own brand and formulas, the 100 & the 50 mix. I use the 100. While I'm sure one smarter than me can use tc3 or something suitable, i'll play it safe and use E-tecs brand and follow their recomendations.

Can one use synthetic 2 stroke oil in an E-TEC??

BRP X-100 actually runs about 80:1 and the EMM automatically increase the oil mixture during break-in which I think is about 2 running hours then switches to the normal oil setting. Do NOT add any oil to the gas as that mixture will lean out the injectors. You can have the dealer program the EMM to run the cheaper TC3. You can also run X100 in the TC3 setting but not TC3 in the X100 mode.

The only reason to run TC3 is have more choices of oil when traveling but your 2 stroke will smoke/stink--something we all try to avoid.

Ok so I can run the 100 mix no matter what setting the engine has then?
I've been running reg two stroke oil since that's what the dealer says the setting was for but then I saw the label saying it was set at the 100 mix from the factory. Does rodger reset these engines? The dealer bought plain old two cycle oil to put in it for the delivery cruise.

Factory sales puts the motors on, and they buy from a dealer near Costa Mesa but are not dealers themselves so they don't have the ability to change the setting from two-stroke mode to X100. You should take it to an Evinrude dealer and have it set correctly to the oil you're going to use. While you could use X100, it will burn through it way faster in TC3 mode and that's expensive.

The oil mixing ratios are irrelevant and do not apply to the E-tec engines. The oil does not mix with the fuel, so you cannot assign a mix ratio to two things that aren’t mixed.

Nor will any modern (early 80's, or earlier) oil injected motor run at any fixed mixture ratio (ie 50:1), because that ratio is continuously being adjusted to suit the varying engine operating conditions.

To confirm some of what has been said above, the engine management computer automatically supplies additional oil for a period of time during the initial break-in period. I noticed a small amount of smoke from the engine at first but it disappeared after around the first hour or so of operation.

The special operating situation where XD-100 synthetic oil is used exclusively must be programmed into the engine management computer by the dealer. This oil has special properties not available from other manufacturers (none that I have seen, yet) and can run at a lower rate of injection than any other oil on the market. This is not marketing hype, the qualities required to do this are just not made by other brands.

I encountered a similar situation in the early 2000’s with the Sea-doo /Rotax engines and XPS-II full synthetic oil. No other oil on the market was formulated to match the requirements for those engines (and indeed, no other PWC engines produced as much HP per cc), so you were stuck with that and nothing else. After a few years similar products did appear on the market from other manufacturers.

If you lift the cowl on the engine you might find a tag around the fuel line near the fuel filter that tells you how the EMC was programmed. If it was programmed for XD-100 (and reduced emissions) that’s the only oil on the market now that you should use, except briefly in an emergency.

Otherwise, if the computer has not been so programmed, any NMMA TC-W3 (=“two cycle-water”) rated oil will be suitable, as well as XD-100.

The E-tec is factory set for X-100. Running cheap TC3 in an engine set up for X-100 will cause the engine to be UNDER lubricated. You need to find a different dealer and dump the TC3 immediately OR reprogram to TC3

Running X-100 mode is EQUIVALENT TO mixing OIL/GAS @ 80:1 mixture.

Hey Bob

That might be the case in the US. Page 20 of my manual (Canadian, yours might be different) says that the factory default is not for the exclusive use of XD-100 oil, and that the purpose of the dealer programming is to set the engine up for the exclusive use of XD-100.

That to me would be the logical way to set it up (less likelyhood of accidentally using the improper oil), unless you were in California or one of the CARB states, which you might be(?)

Yeah--we've been Californicated Mine (08) came from BRP set at X-100

Bob

Bob - Yeah. The rest of the world has a lot of catching up to do in that department.
