I changed my Cav fuel filter today, and I'm glad I did.
It appears the Black Death has returned.

I had a problem 12 months ago so I drained and cleaned the 100lt tank then added fresh fuel. The motor has been running great since.
Maybe the rough ride last weekend on the way to Lucinda stirred some crap up.

I've been using Fuelmaster additive at twice the recommended ratio since. At $80 for a litre for the stuf I was hoping it would keep the fuel clean, it states it eliminates fungus. Not in my tank it doesn't !

Does anyone else use Fuelmaster ?
Any other brand working for you?
