One of the problems we all face is the rate at which the cost of essential goods is escalating. As an example, the last tin of grease that I bought for the stern gland greaser was a little over £3. The current price at my nearest chandler has almost doubled. The same is true of antifreeze. We have not used Antifreeze before in Alnwick because during the fifteen years that we were living aboard, the inboard engine and central heating was always maintained at a comfortable temperature. We added Ankorsol anti-corrosion fluid to the coolant and that worked well when we were using the boat regularly. Now that we live on the land, we need to consider our options - do we continue to keep the boat heated (we did this last year) which is an expensive option when using coal and electricity or do we use antifreeze? The latter will be a major investment because our engine cooling system alone will require 30 gallons (136 Litres) and with the Universal Prestone product that MtB has found, works out at about £35 a gallon, that means that we will need to spend over £1,000 on the stuff. Certainly not a cheap option and for that reason we would want to choose a product that will do the job and last for many years.
