Hi all. Just joined. I wanted to ask a brief q. Wondered what coolant people use please? I was looking at handbook and says 50/50 ethyl glycol whatever that is. I saw motul motocool looking around but looking for something cheaper in a larger quantity that is safe for R1 2005 engine.

Thanks a mill.

Any OAT ready mix or concentate will do . . . . . . . i know this already but like a muppet earlier in the year i went to a bike shop and paid £20 for 2 litres of ready mix for bikes
And i did this with one of the guys on the phone telling me just to buy an OAT generic brand . . . . . which i knew already , talk about throwing money away
BTW welcome to the mad house

welcome in pal, i used this for my jag a couple o months back with just enough left over to do the aaar1 when i can rustle up the motivation [emoji38][emoji38] oh they do smaller bottles too [emoji106]

I'll break ranks slightly on this one.

I'd agree with not wasting money on premium stuff, but if you have green coolant, the safest bet is to buy a long-life green coolant, or HOAT (hybrid OAT).

Yes, you can change to an OAT but flush all of the old stuff out first.

OAT >>>ORGANIC ACID TECHNOLOGY. Had to look it up . Had me fecked . The "H" is hybrid as Moise said .

I personally use Motul MotoCool in my trackbike, with a bottle of MoCool in as this helps run the engine cooler (like Waterwetter)

No, don't get me started on WaterWetter!

Thanks for all the replies folks..I was looking at that Halfords stuff but the label on the bottle carries big warning of don't get it wrong so thought I had better ask people who know first!

Thanks

Yes, you certainly don't want to mix OAT coolant with the old school green stuff. OAT is usually red or orange but not all manufacturers follow that convention.

Welcome to the forum... I’ve been silent on this thread... because all this water and oats stuff.... to me... that’s porridge to me...

I’m as technical as a squirrel.... actually... I’m insulting squirrels... sorry...
Welcome anyway and enjoy your water and oat... I must admit I like to add raisins to my porridge.... but I don’t think they will go well in the R1 [emoji4][emoji1303][emoji23]
