Synthetic Oil In Wintertime

[R H Cotton]

In freezing weather will synthetic oil make a difference in oil injected engines? The E-Tecs seem to give off no oil signals with synthetic blends or conventional oils in cold weather until the engine warms the oil and the signal goes off and the engine will then run at the correct rpms.Someone told me to try synthetic because it does not "gel" like other oils in cold weather. I am by the way using TCW-3RL rated oil like the E-tec manual recommended. I just haven't tried the synthetic yet with the same rating. Any help or suggestions appreciated.

I think that evinrude recommends XD100 for cold weather it is BRP synthetic oil

I am sure that you wont go wrong in this choice of oil.
I use XD50 in my engin but I only fish in the summer. hope this helps.

This is sort of a sidebar comment to your question. Your etech can be dealer programmed to run exclusively on Bombardier XD100. The XD100 is a synthetic and is not economical to run unless in a dealer setup, computer-modifed Etech. There is a difference in oils. The first year out Bombardier found their XD100 would not flow in really cold temps. They modified their oil formula and now all the new XD100 containers have a phrase on the front of the container that says something like "all-seasons" formula. If I had an etech, I would have it modifed by the dealer to run on XD100 oil, causing less long-term carbon problems, (and consume half the normal oil usage.) It's really a good feature to take advantage of.

That's one of the beauties of syn oils; they are tolerant of a wide range of temperatures which makes them superior for extremely low temps, like Mobil 1 now has a 0-40w (I think on the 40 or it's 30) which means it remains liquid down to very low temps (don't remember the number....thinking -65F, but don't want to quote what I don't remember).

On the high end they brag about suitable for temps well in excess of most engine (2 and 4 cycle) internal temps (like 400F comes to mind) which is why they don't break down (like paraffin based oils) at higher temps, protecting better and remaining cleaner longer as a result.
