I have a Vittorazi Moster 185 Plus engine and I've only just completed the first phase of break in. It quite clearly states in the user manual "From 1st to 15th litre Oil 3.0% or 33:1 After the 15th litre Oil 2.5% or 40:1" which is greater than the oil ratio stated in the video. I'm going to continue using the greater percentage.
You probably have an outdated manual. The newest mixes are in the video. Since they change the numbers all the time I guess it's not like you're gonna break anything.
We don't have 95 octane fuel in the US as we use a different rating scale. We average RON and MOR scales. It would be a good idea to clarify octane requirements for Europe vs the US and Australia. It could confuse people otherwise as fuel is rated differently in major markets.
5:19 This video says a "...maximum 10% ethanol ratio" is okay. However, the manual says this: "Vittorazi engines are approved with fuel that complies with the EU regulation UNI EN 228. Fuel 95 RON contain a maximum percentage of ethanol of 5% in volume. The use of inappropriate fuels (with higher Ethanol percentages and / or with lower RON) makes the engines leaner, therefore the problem of the power drop could happen also in normal atmospheric conditions. In addition, as specified in the Walbro carburettor manuals: membranes, rubbers and carburettor seals can tolerate a maximum percentage of alcohol typical of European gasoline (5% ethanol, 3% methanol and 10% MTBE octane enhancer)." Are these two in agreement?
What's that mean? You used both and equals and a greater than. Which is it? Does it equal 91 US so we can use pump gas or is it greater than 91 US so we should use 100ll avgas?
@@TruthHurts2u It means that EU and US gasoline measure differently. But the octane is the same for EU 95, and US 91. In the video they said use 95 Octane, but that is in EU octane measurement. In the US, that would be 91 Octane.
@@acherrington That's correct. Europe and most of the world us RON to determine Octane rating. US uses PON which is a calculation between RON and MON. US 91 is the same as EU 95 and US 93 is the same as EU98. It is what it is. All this info is available by research.

@@medotaku9360 Thanks for your reply. I have been gradually reducing the oil mix and will follow the latest video.

I use aspen 2. stays good for 10 years no ethanol, no carbon build up, no toxic fumes and no residue in your carb. expensive but the best by far.
Aspen 2 is great!

If im using avgas, are the oil mixture ratios still the same?
Note: 95 octane EU => 91 Octane US.

@@acherrington Thank you. I've seen so many contradicting information about this motor when it comes to what fuel and what oil mixes to use.

Thanks for the info, Merica.
Hi Sir , useful video.. Vittorazi available in india ?
Yes..it is!
