Additives

Our car hand book tell us not to use additives 

Nope. My handbook expressly says to avoid them.

There was a similar thread not long ago, rjb. You might find it if the wind's in the right direction and there’s an R in the month.

This one....?

Yep, I think that’s the one. Goodness, and there’s no R in May 

just use premium fuel.

Just use supermarket fuel👍🏻

Darn it Tinny trust you to bring common sense into the discussion. Next you’ll be saying the Earth isn’t flat😂😂

I have had various diesel vehicles for around 30 years now, and have never used premium fuels or additives and have never had a problem using mainly supermarket fuels with the occasional cheapest convenient branded top up.

It is flat - in Norfolk 

Following the amazing results people are seeing on most of the major motoring forums, I tried mozzarella cheese.

I've been "cheesing" now for nearly 6 months.

My engine is running much more smoothly and my mpg has gone up 10-15 mpg.

At my last service, my mechanic said he had never seen such a clean engine, the DPF, EGR, Cat & Panametric Fam where like new!

And at MOT they had to test the emissions twice, because the could not believe how low the emissions where, better than the brand new Euro 7 standard.

Now you must use a good quality mozzarella, Cheddar or Red Leicester are no good.

I'm telling you, you wont regret it....cheese up now.

Do you research on the forums, the anecdotal evidence is all there!
