Diesel additives..... Fyrex Ci ?

Has anyone tried marine 2 stroke oil at 1:200, low or zero ash?
It's been used in diesels for many years to achieve the same thing at a fraction of the cost.

Yes, it has been debated here. There is an old thread somewhere. However, I would use only designated diesel additive suitable for the late model diesels equipped with the DPF.

It's all very scientific these days so I don't dabble in additives any more in modern diesels.

It's still the same old diesel at the pump with less sulphur than it used to have, with whatever additives happen to be added, regardless of the high or low tech engine it's about to be used in.
Some of the additives sold in the auto shops are less than convincing and will never go in my tank, regardless of their sales pitch.

I guess what i'm saying is who knows what's in the additives sold at the auto shops?

[Ryeman]

Does anyone know if dealer/s use any additives?

[Transporter]

They do. For sure in petrol and soon they will start using the diesel additives. Even the owner's manual says use the fuel additive.

How's that with they years of saying don't use any additives?

Stealers will flog anything that makes them money.

But which vehicle owner's manual says to use additives??

Yeti manual
"Fuel additives
You must not use fuel additives, so-called “flow improvers” (petrol and similar products) in diesel fuel."
"CAUTION
It is not permitted to add the various fuel additives on the market, including pet- rol, to diesel fuel in order to improve its flow properties."

For petrol engines:
"Fuel additives
Your vehicle can only be operated with unleaded petrol, which complies with the standard EN 228 (in Germany: standard DIN 51626 - 1 or E10 for unleaded fuel with octane rating 95 RON and 91 RON or DIN 51626 - 2 or E5 for unleaded fuel with octane rating 95 RON and 98 RON). These meet all requirements for troublefree engine operation. Therefore, we do not recommend the use of fuel additives."

I've definitely saw it in one of the late model VW I've serviced lately, could be Jetta. I will take the snapshot next time.

I wonder if that's a statement the factory would support or just a dealer profit driven statement?

It was in the factory owner's manual, the car was most likely a 12/2013 Jetta TSI.

I'm using the fuel additives in both engines and as long as you use the right one and as intended they do work and the engines are more efficient for longer compared to those who don't use anything in the fuel, do 5,000km per year or even less.
I use even the oil additives when it's needed and in our cars I use Liqui Moly MOS2 or the Engine Protect, right from new.
