Summer Diesel

mikeecho

So.. I've been running my car on summer Diesel .. but with the recent drop in temp, I topped up with some Diesel from the forecourt.
I've a tank with 60% summer and 40% winter Diesel.

Should I be ok ?

Do not worry, here is no winter on Ireland. The best "winter additive" for diesel are to keep the tank so full as possible. You should worry only if entire week are constantly (24/7) -5 degrees or less. The winter diesel have typically less paraffin. The paraffin helps little to lubricate cylinders, injectors, high pressure pump. If you buy the nordic diesel and use it on over +5 degrees weather, you will ruin the engine. So be careful.

You will be fine, but if you are worried about it add some anti gel diesel additive

Lads I'm driving diesel cars here for over 40 years (including during some severe winters) but this summer v winter diesel is new to me.

It may get a bit wintry in the coming days but I think you are worrying about nothing.

A lot of people don't read the manual that came with their diesel car and don't wait until the glow plug light goes out before trying to start the car in cold weather.

Did you read the wiki link ?

That'll explain winter/summer Diesel



I'm just curious, if the Diesel will mix completely, and have an overall lower gel point, or will the summer Diesel with a -5c° cffp turn waxy

With reports of -7c° possible, I don't want to be caught out.

I don’t think that’s a thing anymore

It is. But most cars start the glow plugs when you shut the door the first time.

I remember in the 80s loads of people's home heating diesel froze, (well , turned into a thick useless gel),
