Interesting, i use 1oz fp+ with every fillup ... figure it can't hurt, and you honestly can't trust the garbage in todays gasoline

 

Well, that should explain why modern cars don't seem to last as long as cars made in the 80s 90s ...

Go green! More break downs, more new cars! Yay

It also proofs that we should premixed whenever we could ...

 

Hmmmm.

 

Interesting indeed.

 

I don't have conclusive factiods wrt reduced engine life, but will say in my rather extensive automotive grapevine, I've yet to hear of even one fuel injector failure. However, most injectors on the road today run at much lower pressures than new common rail gas/diesel systems, so the new ones may run into trouble much earlier.

This article does make me at least feel better about my premix though!

 

Yeah premix is key but it has me thinking about using Lucas UCL again.

 

I use Lucas UCL every 5 fill ups on all my cars.
I've never contemplated the combined effects of premix and Lucas. I didn't even try because I'm not well versed in chemistry. Yet I still wonder if combining them is additive in effect or if they mix to become something else...

 

I just use Group 5 motor oil, which has polar molecules that stick to metal surfaces better than older oils. Should be fine without pre-mixing -- though I do have an S2 engine, so my lube system isn't borked from the factory. That helps a lot too.

EDIT: Notably, Group 5 motor oil has exposed sulfur molecules on the ends of the molecular chains, which I suspect may help make up for the lower sulfur content in the gasoline. In any event, though, gasoline isn't supposed to do anything except burn, and burn as cleanly as possible, so if there's trouble with premature wear in engines then the engines need to be redesigned. There are lots of metal coatings available that can greatly reduce wear.
