asquaddie Posted April 7, 2017 Share Posted April 7, 2017 Guys This is a genuine reason why I'm asking this question and I'll explain after I get a few answers back: If you own a fairly new Moster Plus 185 what oil ratio and what oil do you use?? Many thanks Tony Quote Link to comment Share on other sites More sharing options...
Guest chrisg547 Posted April 7, 2017 Share Posted April 7, 2017 1.5% Motul 800. Quote Link to comment Share on other sites More sharing options...
admin (Simon W) Posted April 7, 2017 Share Posted April 7, 2017 Castrol TTS 50-1 on the 2 school Mosters (combined hours of over 100) and rising fast. No problems at all. I have always used TTS and have never had a seized engine in 10+ years of flying various engined Paramotors. SW Quote Link to comment Share on other sites More sharing options...
papagyo Posted April 7, 2017 Share Posted April 7, 2017 2.7% Motul 800 works great. Quote Link to comment Share on other sites More sharing options...
asquaddie Posted April 7, 2017 Author Share Posted April 7, 2017 So far all three are different!!! Quote Link to comment Share on other sites More sharing options...
tim9227 Posted April 8, 2017 Share Posted April 8, 2017 Hi Tony. I've always used Castrol T2 racing oil. 100ml to every 5ltrs of petrol. Got about 70 hours on it now. Tim Quote Link to comment Share on other sites More sharing options...

Hann__ Posted April 8, 2017 Share Posted April 8, 2017 113ml of Castrol Power 1 Racing to 4.5 litres (1 gallon) of fuel. 2.5%. Quote Link to comment Share on other sites More sharing options...
AndyB Posted April 8, 2017 Share Posted April 8, 2017 2 stroke engines all use a ratio of between 1:40 and 1:50 oil:petrol. 1:40 is 2.5% or 25cc per litre. 1:50 is 2% or 20cc per litre. And of course, the larger the petrol can you use, the more accurate the measuring. I use a 20 litre can and always refill it when it gets below half full. I use a separate 10 litre can to refill it, so add 200cc each time (Thor 190). If in any doubt always go for a higher oil content. Whilst it may cause a little more carbon, it will help prevent any disasters! Quote Link to comment Share on other sites More sharing options...
asquaddie Posted April 8, 2017 Author Share Posted April 8, 2017 Simon - Any reason why 'you' use 50:1 and not the recommended 40:1 for the Moster? Tony Quote Link to comment Share on other sites More sharing options...

But after getting Motul 800 and it being so good. I was recommended to use 1.5%. I have to say my plug is in a better condition than before as it always looked like i was running too rich (with the TTS). Quote Link to comment Share on other sites More sharing options...
GR002 Posted April 10, 2017 Share Posted April 10, 2017 This is a good topic. How many hours have you done on the Motul 800 at 1.5 %. I always wondered why The Moster was 2.5% when other engines I have had were 2% Quote Link to comment Share on other sites More sharing options...
AndyB Posted April 10, 2017 Share Posted April 10, 2017 Be careful reducing oil content and be very wary of oil manufacturers claims. I used to manage a Petrochemicals complex (makes oil and petrol). All oils made from crude are very similar. They have a range of molecular weights and are usually made up of molecules with 17 to 34 components ie. they have a distribution of size. Synthetic oils have molecules manufactured to have a specific number of components and have a very tight distribution around a specific molecular weight. Synthetic oils are better because most of the oil is at the target molecular weight. All oils have additives to improve performance. I remember well a BP oil expert coming to talk to us about the additives as well as the use of after market additional additives. His view....there is very little difference between oils! All 2 stroke oils must meet the minimum spec defined by API TC or ISO EG and these modern specs are very good. Manufacturers have determined the oil ratio required to match the tolerances and operating range of their engines. It is a balance between getting lubrication and not getting ash/gum/crap build-up. I would be very wary of changing the spec they have given. One final point. There are racing and castor based oils. These sometimes give improved performance, though might not be enough to notice, and there will be greater coking requiring more frequent stripping! 1 Quote Link to comment Share on other sites More sharing options...
tim9227 Posted April 10, 2017 Share Posted April 10, 2017 Would be interesting to know how many motor failures there have been due to poor lubrication, I have yet to come across any . Most seem to be due to poor carburation. Is your motor going to be fit for the Bore Tony. Tim 1 Quote Link to comment Share on other sites More sharing options...
asquaddie Posted April 10, 2017 Author Share Posted April 10, 2017 Not really 100% certain mine is that problem. Going to reduce the oil ratio next time and see if that works. Just got the motor back today, but have man flu. So hoping to have a fly maybe Thursday I'm be going even if the motor doesn't Tony Quote Link to comment Share on other sites More sharing options...

tim9227 Posted April 10, 2017 Share Posted April 10, 2017 I should stick to Vittorazzi spec to avoid any warranty issues. A slightly stronger mix should help eliminating partial seizures assuming piston clearances are correct but if damage has already been done it'll be a new piston and barrel required.

Tim I guess I am aware of this, but many other guys here and on FB have mentioned they use 50:1 (even less) and I did get the recommendation from Parajet - even they used 50:1 on my machine (which is documented). In the past 6 months, Tom's had more air time on my machine than I have and I was using 40:1. 11 hours ago, cas_whitmore said: if what works tony' did you find out what the problem was with your motor . Cas - As per the original problem - starter cord seizing after 10 - 15 minutes flying. Then it's OK after 45 minutes. Very weird. So, not really yet, need a few short flights to confirm the ratio, with plenty of pug checking Quote Link to comment Share on other sites More sharing options...
Ivan Posted April 11, 2017 Share Posted April 11, 2017 (edited) Few years ago I mailed Vitorrazi asking about Motul 800. They do NOT recommended to use it. Motul 710 which is recommended in manual has different burning temperature and burning time. Therefore I use only Motul 710. 2,5% Edited April 11, 2017 by Ivan Quote Link to comment Share on other sites More sharing options...
asquaddie Posted April 11, 2017 Author Share Posted April 11, 2017 (edited) Nice one Ivan - that's going to set the temperature even higher....... Edited April 11, 2017 by asquaddie Quote Link to comment Share on other sites More sharing options...

asquaddie Posted April 12, 2017 Author Share Posted April 12, 2017 Ha Ha, Not what you're thinking about sorry, well, I'm not into that. I've seen a new check list on the take off procedure. The last one is 7. Check for straying pug dogs crossing your take off path. I guess you all do this without thinking ..... Tony Quote Link to comment Share on other sites More sharing options...

Guest chrisg547 Posted April 16, 2017 Share Posted April 16, 2017 (edited) I've now used about 2litres of oil at 1.5% mix so I reckon somewhere between 20 and 25 hrs. This is a good topic. How many hours have you done on the Motul 800 at 1.5 %. I always wondered why The Moster was 2.5% when other engines I have had were 2% Edited April 16, 2017 by chrisg547 Quote Link to comment Share on other sites More sharing options...
