First tank is in with the grill block on. Car was running a 20/80% veg/Diesel mix
670.1 miles for 52.58L of fuel
Giving imp MPG of 57.94
thats a 0.37 mpg gain, and I'm happy, bearing in mind the traffic I've had to deal with this week.
Now running 30% veg oil..P&G too.. gonna shoot for 58.5 imp mpg!
Weekend may also see a swap of battery (current one is undersized) and a thermostat replacement- as the car is running colder than VW intended, even with grill block.
Thermostat looks like a likely suspect..
And maybe a raid around the unit to see what parts I can pilfer for modding purposes
