The issue with Morgans is basically in two parts. Engine and the rest of the fuel SYSTEM.
Engine. Over the years MMC have used many engine types and the details of which engines are ok is straight forward.
The unknown is the rest of the system outside the engine. It looks like MMC have made the CX E10 compliant and some earlier models too. BUT, as in other MMC foebles the questions remain about components with rubber type composition and seals. Pipes, pump etc..
As I stated elsewhere I am searching for clear, properly gathered data about the effect of ethanol on rubbers. How does it affect rubber and how quickly?There will be differing severities from pure ethanol down to lower concentrations.
I have a 2002 Plus 8 and the ENGINE is given ethanol clearance. As in the info on official sources for Morgans it is unclear if older cars will be ok. Basically a get out of jail statement as MMC cannot confirm what ethanol resistance the ever changing components have.
Empirical evidence of older, high mileage cars running ok on quite high ethanol level petrols suggests no increased problems. Rubber deteriorates anyway so how do we know, without proper scientific tests, that failures are ethanol related? Think about renovating older cars. Rebuilding fuel pumps, renewing old, cracked and perished fuel pipes is almost mandatory.
I may start some tests myself. Get various ethanol containing liquids from the pub as samples.
