Engen Fuel Quality?

[Bliksis]

do a test. buy spark plugs. every 1000km take a photo of them. buy another set do the same and only drive on engen fuel.

Yes there is a huge difference on fuel additives. Caltex always had the best additives. kept engine cleaner. But changing to engen after a a couple of tanks of Caltex you see the better fuel consumption. So I ran 1 tank Engen every month.

I still changed plugs every 10 000 km. I hate regapping as you can crack it and send a little piece of metal down the cylinder.

I didn't know re gapping was still a thing.

Site owner here, wont mention brand just cos.

We've had numerous issues like this. Latest is a long time customer, Mercedes states that the GLA200 was damaged due to contaminated fuel, However the customers other vehicles, including a GLE43 have no issues. Its not the first Merc that has supposedly had this issue at our site and others, even other fuel brands. Generally, its a C200, guess the GLA uses the same engine. No other cars have ever had an issue like this at our site.

Damage includes injectors etc. We take all precautions when receiving fuel, only buying from our OILCO, doing water tests twice a day as well as before and after deliveries.

Does anything get added?

Anything older than iridium plugs yes.

no, its branded. Have an ongoing supply agreement with the OILCO.

Yes, all fuels have some sort of additives. the ones that dont are the routers and bulk resellers. They either bringing in Diesel accross from bots, or getting the raw fuel from the same gantries that we use, just off different tanks with no additives.

I meant, do you add things to the fuel when you get it? If so, why? I ask because I don't know.

No, As far as I am aware, none of the legit dealers are adding anything to their fuels. Any addititives comes already mixed in when we receive a delivery. Generally, its injector cleaners and the likes, as we are told "the new formula cleanes 80% better than what we had last year."

I've experienced that with Engen my fuel consumption is notably worse than other brands over tank vs tank. This is over 3 different vehicles over a course of 10-15 years. Not sure if its bad fuel or compensation for slight lack of engine performance while driving.

Engen leaded fuels however burned the whitest!
