Oil mix for a 200 XR2

[Ring Owner]

Can someone please confirm what oil mix I should be using on an late 80's, stock, 200 XR2?

I have seen and read several conflicting report, anything from 32:1, 40:1 or standard 50:1.

This year, for the few times I had her out I was running with a 32:1. She is currently running below max RPM so have to play with the prop. However, I was wondering if I was over oiling her as well.

I certainly have no objection running 32:1 but would just like to be 100% sure it is the correct ratio

Cheers

If you are racing Then you need to run on 40-1 If it's just pleasure Then you are Okay to run on 50-1 You will be quite safe Most of my customers run 50 to 1 And never ever have a problem Otherwise you Will oil your plugs up Hope this helps Many thanks Keith

Really, I run fully syn, at 50:1 TCW3 oil and costs around £3-4 a litre

Thanks Gents - that makes more sense.

I used to run my old 150 on 40:1 to be on the safe side so 32:1 always did seem excessive since I have no plans to over rev the old girl.

Can't disagree with the price of oil - 5ltrs of Quicksilver 2 stroke is knocking me back around 32 quid a pop at the moment

should have read semi syn - £68 for 25 liters from a company called rye oil, have been running for the last few months and been absolutely fine

Do not run synthetic or semi synthetic on a steel lined motor ( XR2 etc) you need a good mineral based 2 stroke oil as the synthetic stuff is too good and will line the bores causing you to lose compression.
I would run at 40:1 unless you are going to be revving continuously around 7K in which case you need to be running 32:1 Remember though that to use the full power of the XR2 you need to be in the high 6K's.

Good luck and happy boating

Manuals for the race XR2s say 32:1 and merc hi performance blend oil or quicklilver prem plus if you cant get the blend. Guess it's horses for courses though.

Rock Oil is fine at 50:1 & 6 squids a litre.

Don't really know why you're so worried about you're a oil quantity As long as you put a minimum of 50 to 1 and you will be fine it's not this which will destroy your engine it will be over heat water lack of blocked carburettors or timing out The rock oil is very good just remember oil doesn't equal power take an engine apart which has been on 50 to 1 and you will see there is oil everywhere my customers one perfect on 50 to 1 it will not be the audio mix which destroys your engine if you run 50 to one or more this is just my opinion what do I know I've only been doing it for 20 years and never had an engine blowup on 50 to 1 🤓🤓🤓🤓

XR2 is a 150 not a 200

Cowes Poole Cowes last year ran 50:1 mineral oil. It was fine... SST120 powerhead...
