Who needs correct havoline XLC coolant for Yanmar engines?

[FullCircle]

I have been trying to source Havoline XLC coolant, the only one recommended for use in latest Yanmar engines.
The local Texaco petrol stations can sell me a banana or a newspaper, but not XLC coolant. Sheesh.
Anyway, I have availability of either 12x1 litre bottles at £7.01 +vat or a 20 litre drum at 130 quid.

Anyone out there wish to share this, or shall I just wait for French marine to deliver it to me at 11 quid +vat a litre? Can deliver within reason, or work out something in the Essex/Suffolk area....

This is a new one on me, I thought 50/50 antifreeze/fresh water was the stuff for engine coolant. What's supposed to be so special about Halvoline? Thank God I've got a SW cooled 1GM10.

It is a high-end product, with supposedly very fancy anti-corrosion properties, but at heart a glycol-based coolant. It can certainly be mixed with other glycol antifreezes. But maybe there are warranty issues for the orginal poster.

Reminds me of a mate years ago who followed his Ducati's handbook to the letter and privately imported Agip oil from Italy when it wasn't available in the UK. Tougher then, of course, before the open market. But still a waste of money.

Big warranty issue on 3YM30 engines, as Jeanneau had 90 million gallons of the green stuff at the factory, so used that.
Result is that the heat exchanger gets clogged with silicates, and off goes the alrm, just when you dont need it.
I have had my coolant replaced under warranty, but the overheat persisted. In fact it persisted when I was crossing the TSS at Dover/Calais on a windless day with a row of killer ships trying to get me for an extra 5 points.
So, French Marine replaced the Heat Exhcanger under warranty. No questions.
Sadly its leaked a bit over the winter, so they are coming back to fix the leak and top up.

I just wanted to keep 3 litres in stock fopr top up and coolant change when required.

Please do not assume that its mixes well with others in this application. It doesn't.

I have seen this from the opposite side, and it is particularly the case with Itallian machinery. Suppliers of fluids pay a lot to engine/machinery manufacturers to have their product promoted in the manuals and on stickers attached to the machinery. In almost no case is there a technical reason for this, particularly in the case of lubricants where it is a condition of the specification that all must be miscible in a range of proportions and basically do the same job.

When Shell took over from Agip as fuel and lubricant supplier to Ferrari (after paying big bucks for the privilege), there was a great deal of resentment from the Ferrari staff on the ground. A colleague of mine visited Modena for a two-day technical meeting. He wasn't even offered a cup of coffee, much less lunch or dinner! It was widely held that Shell's annual fee to be supplier paid Michael Schumacher's wages, to give you some idea of the sums involved.

Oil is oil, lube is lube, coolant is coolant, anti freeze is anti freeze.
Maker,s Name / Label is borrocks.
Specification on said container is what is important
"Yahaha oil Suzuki oil Merc oil borrocks, those peeps don.t make oil!
As vyx-cox says the product is "Promoted".
So blimp the Havoline bottle, look at the Specs and use/ source any other Brand that is the same.

As a Ford Powertrain design Engineer, I agree mostly with what you say. However in this case, it is finding the correct level of coolant and I am not going to be another guinea pig, as a new engine is over 7 grand, and they would now refuse the warranty if they found anything other than recommended, as they have had a very high failure rate.
I fully understand the issue, and it is the levels of silicate in the coolant product that have a poor interraction within the fine matrix in the heat exchanger. So, no, I'm afraid it isn't bollocks, if you will pardon the expression.
