which two stroke oil for 1948 engine?

[loving_allsorts]

Thanks to all who helped me out with my previous enquiry
my next few are:

1. Which two stroke oil do I mix with the unleaded to make the fuel?
2. Where is the cheapest place in the uk to get this (either local to stafford or other wise to include postage to stafford)?
3. I believe, as my engine is 1948, that it will be 10:1 in ratio mix. How long will this mix last in a gerry can before it is unusable? any ideas?

Many thanks

Mark

Hi Mark welcome to our community
Firstly the issue of two stroke oil has been done to death on the site just type in the search bar. You are correct with 10; 1 mix and only mix up just as much as you need. Most petrol loses its volatile essences after a few weeks. Most of this information can be found on the main site and on other posts. Good hunting

Current recommendation is to use a TCW-3 two stroke outboard engine oil. Cheap it is not though.

Back in 1948 I expect the recommended oil was a straight, SAE 30 Oil ... (but you should not use modern multi-grade oil.) Later, if not in 1948, the recommendation would have been a 2 stroke oil ( my 1973 owners handbook mentions several well known brand names).
I'd guess you are also likely to find some garden machinery oil that claims to be suitable for small outboards.

the current recommendation remains TCW-3.
Quicksilver is the brand you are most likely to find. In the USA Walmart's own brand is popular but as far as I know Asda in the UK dont sell outboard engine oil

I confess that i dont mix fresh fuel for the Seagull. Every year I end up with a tank full of 50:1 fuel for my Evinrude. I transfer it from the plastic tank to 2 tightly capped metal cans. These I store over the winter. I only store full cans and any in excess I stick in the car.
The following year I use 1 can full mixed half and half with fresh mixture for the Evinrude. The other can I use with extra oil added as necessary for the Seagull and the lawnmowers.
I always filter stored fuel before I use it ... once I did not and ended up stripping a carb down on a breezy night off Cowes

The Seagull and the Evinrude seem happy with this regime but I do know if I try to keep fuel longer than that the Seagull is not happy nor is the Flymo. I think it probably does run better on fresh fuel though. When we get 10% alchohol in all our petrol I will probably have to change my ways or at the very least use a fuel stabiliser.

I thought of to use propane but diesel is lubey as it is, and you could run propane injection on one Im sure. I was thinking it would be cool to have a propane sled...without even thinking that a 2 stroke engine runs mixed oil lol. Put some diesel injection on a propane engine! hah (that was a joke)

So what you are all saying is probably diesel would do instead of a 2 stroke oil and petrol? Thanks for all your help, I'll do that.



Only joing, Thanks for all the advise folks. I've bought some of the TCW-3 from the internet. I'll mix a tank at a time and take a spare tank with me.

Thanks again
