Hog Head Posted August 14, 2010 Share Posted August 14, 2010 What method is used to calculate the octane of Thai petrol? RON MON Average of the above? I am setting the compression ratio of my 2332cc VW engine and need to know how the AKI is claculated Link to comment Share on other sites More sharing options...
katabeachbum Posted August 14, 2010 Share Posted August 14, 2010 RON, as in Europe Link to comment Share on other sites More sharing options...
Hog Head Posted August 14, 2010 Author Share Posted August 14, 2010 That is bad news for me and my dynamic compression ratio calc 95 RON = 91 AKI or an average of RON + MON as used in the USA Link to comment Share on other sites More sharing options...
katabeachbum Posted August 14, 2010 Share Posted August 14, 2010 That is bad news for me and my dynamic compression ratio calc 95 RON = 91 AKI or an average of RON + MON as used in the USA fuel is crap in LOS Modern environmentalfriendly car engines need 98 RON, not available in LOS and 95 RON is not available in LOS without 10% Ethanol blended in, Gasohol E10 Octane booster or buying barrels with 107? RON at 40-45? baht/litre Most bigbikes have the same problem now Link to comment Share on other sites More sharing options...

Even Shells 95 V Power is now blended with Ethanol, but as I recall less than 10 %. Link to comment Share on other sites More sharing options...
Hog Head Posted August 14, 2010 Author Share Posted August 14, 2010 I have recalculated the dynamic compression ratio to work on this crappy fuel. Not happy, but this is all I can do until E-20 becomes more readily available Bring on E-20 or better yet E-85 and then I can really increase the compression and suck back even more of it. At the same time I also want Shell V-Power petrol back for my bikes but that is a politically driven impossibility in the LOS Link to comment Share on other sites More sharing options...
