Environmentally friendly oil for 67 Johnston folding motor

[kms]

Hello all. This weekend I was fortunate to acquire a lightly used, very well maintained 1967 Johnson JHF 22C 3HP with case, as well as a second identical parts motor.

It purrs, and I’d like to keep it that way, but would also like to use the friendliest oil I can get. I am definitely NOT an expert, but I have done some research. It looks like I should be using an oil that is both "readily biodegradable" and "tc-w3".

I’ve seen that Phillips66 made Synjex (do they still?), but can’t find it for purchase. I’ve seen other products from companies I’ve never heard of, and thought it best to ask people who know what I could/should use.

Thanks!

She looks like a real beauty!

TO keep her that way, ensure you run at a proper fuel/oil mix, with a good TCW3 oil. Synthetics even better. Please don’t let Bob the Builder down the street convince you to run that at a 50:1 ,mix! 24:1 would be my minimum. I run mine at 16:1 as I share the gas can with other small hp motors requiring 16:1

My brand of choice is the BRP XD30 for my oldies, but there are other good oils out there as well. A lot of guys on here run Penzoil synthetic oil. I find the XD30 burns cleaner, with less odour and less oil slick. Your results may vary.

Great find!

G-oil makes a biodegradable TC-W3 oil, check out their website, I think it’s available on amazon:

For the little bit of fuel that will use, cost shouldn’t be a big concern. From the website:

G-OIL® 2-Cycle Green Outboard Engine Oil is a superior performing engine oil engineered for all makes and models of outboard engines and personal watercraft as well as ULTIMATE BIODEGRADABLE, the highest biodegradability ranking as determined by ASTM Standards (2.1 ASTM D-5864)

Belray also makes a biodegradable TC-W3 oil:

Even though the motor looks excellent, be sure to check the coils as many are cracked just from age.

Looks like one I sold a few years back. Where did you find it?

First, thanks for the reply. I wonder about the ratio you mentioned. The motor also came with a pristine original manual that clearly says 50:1.

Yes, the manual clearly says 50:1. What it doesn’t say is the powerhead is relatively unchanged from the 1952 version. Trust the members that are trying to keep the motors alive, not the bean counters. Its always easier to add extra oil than rebuilding the powerhead… if it doesn’t melt or blow up.

If you have too many, AND not enough, you're a collector.

Thanks for the recommendations and the advice. I will be sure to check the coils.

Please don’t think I was arguing. I am quite certain that the members here know their stuff.

Thanks!

No worries. Just being sure.

South jersey from a retired auto body mechanic. He got it from the daughter of the original owner about 10 years ago who hadn’t even put gas in it. I will check everything, but he ran it in a tank for me and it started immediately, and ran beautifully. His garage had other projects going on, but was clean enough that you could eat off the floor. The identical parts motor is possibly fixable too. It was a very lucky find.

Btw I also intend to use it. My only other outboard is a 2.7hp cruise n carry, which my daughter called noisy, stinky and awful.
