VW fuels - Premium or super

[jhonnieblue]

guys,

been back and forth with this topic.

What fuel does most VW cars use and what type do you'll use
I know the the Mk6 jetta uses only Ron 95

My B7 passat has on the flap
95/91 Ron/roz
Ive used both with no noticeable difference
slightly better mileage with the premium
however ive use treatments - redline SI-1 which boosted the mileage to about 850km off a tank of super
from what ive read, Premium and super fuels have different chemical additives to treat fuel systems- thereby premium being billed as the "cleaner" fuel.
lots of these additives are similar to that contained in the high spec fuel treatments, redline, techron etc but at a lesser conc dosage. Basically the equivalent of residual treatment thoughout fuel usage

anyone care to share their experiences?

All Premium and Super fuels are made in Petrotrin then sent to Unipet and NP. Premium and Super use the same components: Alkylate, Isomerate, Platformate etc with no chemical additives to treat either of them "cleaner". The only difference between Super and Premium are the ratios of the components used. RON 95 may just have a lil more alkylate for example but other than that neither is "cleaner" than the other. Each component has a different RON with Alkylate having the highest of the components.

Your Passat can use Super because it is above the minimum RON required by your engine (91) which is why you have no issues running Super.

Premium gives you better fuel economy because the engine adjusts timing when it recognized it isn't knocking on it. Both fuel grades will not damage your engine. I would stick to super as I'm sure the difference in mileage obtained with Premium doesn't match the difference in price compared to Super. The fuel treatments increased the octane number of the Super in your tank resulting in less knock and adjusted timing by your car leading to the increase in mileage. Pretty much the same scenario as Premium.

Anyone ever tried super in the new Jetta ?

[Allergic2BunnyEars]

Considering that it says minimum 95 I would love to hear from those who use straight super in theirs.

This document goes against my gas tank flap so who knows. Engine code CAVD.

Well Bunny the speed and continued acceleration, someday I saw you turned by Trincity Lights on the highway, I thought is diesel you running. LOL

I've only ever used premium so far. Higher cost of fuel was factored in when making the purchase for this car so it's no surprises at the pump really.

Maybe one day I will try a 1/4 tank on super and see, but not this day.

Does your car call for 98? or 98/95?

You wrote this like a chemical engineer working R&M.
Hmmm

98/95. I thought it was 95/91... my mistake

[purple_heart77]

No 92 for you. You already on the lower requirement. You may only be missing a little more power and slightly better fuel efficiency as per above conversations.

Might try 92 on my B6

[syncrod]

somebody try the super na, report yuh findings.

[tr1ad]

Why don't you try it

[syncrod]

Lol I fraid

[Allergic2BunnyEars]

Friend of mine said he knows a mk6 Jetta owner running FULL super for months now. He has noticed decreased fuel economy but no other issues have reared their heads. Drives economically though. No hard mash out or top speeds on the highway...

[aatwell]

We need to get this guy in this forum .................... would love to hear about this

[tr1ad]

Want euro ride but can't buy the right gas?
Riteeee

[DVSTT]

Any noticeable difference in acceleration when you floor it or throw it into sport mode?

Car works fine still runs like a beyotch
