I thought I saw a discussion on this forum about fuel but I can't find it for the life of me tonight. I've had a 2014 VR6 R-Line since I bought it with around 42k miles and now I have roughly 109,000. I've never had any problems or issues. I maintained it at a VW dealer until the 10 year warranty was over and I was fortunate that a former VW tech from the east coast moved into my little town and opened up a VW specialty garage. I never did get around to asking him about fuel when I had him install new brakes-rotors a few months ago. I have my eye on another Touareg - a 2017 VR6 Wolfsburg with 67,000 miles. Asking price is $15,995. This would be to replace my wife's 2014 Jeep Wrangler Unlimited that she's had since it was new. Looks great but with 185,000 miles it's starting to do more than nickel and dime us. She drives a lot more than me and I know I read where for some reason Touaregs after my 2014 did not say they REQUIRED premium fuel. I've always used premium but in my neck of the woods that's pretty close to an even dollar extra over regular - or about $25 extra per fill-up. Is premium required on the 2014? If so, what changed on the newer ones that eliminated that requirement? Appreciate the advice.

A quick web search shows regular is fine for daily driving, and premium is recommended for towing.
What does the fuel door placard say? That's what I'd go with.
Even so, the ECU on these is sophisticated enough to retard timing with low grade fuel and avoid engine damage (in a pinch). But I'd go with what's recommended on a daily basis.

Mine is a different generation, but on the fuel door it says that recommended octane is 98 (I think this translates to 93 in the US), but 95 can be used but with reduced performance. So I use 98.
I'll usually use the rating on the fuel door of a car in hot weather, performance driving, or towing... but in cool weather commuting usually go 2 points down from the recommended rating only if I can confirm the fuel economy doesn't drop, which tells me it's not consistently holding back the timing.
My Porsche requires 93 octane, and 91 is the highest they sell in my state unless you're buying it on site at a race track. Works fine, zero issues. The recommendations are generally chosen to entirely eliminate knocking under the most extreme heat/performance driving conditions- so going down a little on a vehicle with a knock sensor system is fine.

I run the 91 as well that’s all that’s Available in my state as well… I notice when I run 87 starting is rough. Then is fine but I don’t do that anymore I use 91.
