I had and have a Mk5, Mk6, Mk7 GTI’s and Mk7 GLI all stage one tuned. NO MECHANICAL ISSUES AT ALL in any of these. All 5,000 mile oil changes. No short trips at all. If I need to go 2 miles, I drive 10-15. No full throttle until 180 oil temp but plenty after that. Lied about the No issue thing. Needed a new clutch in the Mk7 GTI (tuned) at 3,000 miles. The replacement SRE clutch is doing great at 50,000+. Always garaged. Did use lots of tires.

detergents don't do anything for your pistons when they're working with shitty winter gas that's been sitting in the tank for weeks. bobistheoilguy is a hell of a drug

the ecu "handles all of this" by pulling timing. log a car running even mediocre 91 and you'll see constant timing retard. yes, it will keep the motor alive by doing this, but you'll foul out spark plugs quicker, kill your cat quicker, etc. over 100k i'm sure that's going to be noticeable. these things will pull some timing even on decent 93. all of that is just plain old driving reliability, not to mention the reduction in chance of detonation. yes, a stock car is pretty unlikely to blow a piston, but running better fuel will reduce that chance further.
I have logged my car many times as well as other vehicles and have never seen "constant timing retard" running 87. How then are all these vehicles running around just fine with 100K+ miles on turbo motors that ran nothing by 87? where are all the fouled plugs and killed cats? There aren't any b/c it doesn't matter when the car has been tuned for it. One of the guys around here has a wagon like mine and tracked the shit out of it with APR's 87 tune without issue. The OEM isn't telling you to do this if it would be highly inefficient - they have every incentive in the world to make their cars run well and efficiently. You just don't maximize power, that's really all and that is ONLY if you are getting that timing pull etc. to allow headroom for running 91/93 and reduce it. Folks want so bad for 87 to be the boogie man but it just isn't the case. Some stations here it's up to $1/gal more to run 93, no way I'm running it if I don't have to. My son's Lexus calls for 91, it's had 87/89 it's 15 year life now at 145K just cruising along.

91oct "RON" = 87oct "AKI", unless the Lexus was turbocharged... I doubt it requires our "91" ? its probably asking for RON 91..... which is what you are filling it up with....

I'm aware of this difference. My 2008 Lexus calls for 91 AKI/(R+M)/2 "premium" fuel in the U.S. Except for a handful of times, this vehicle has been operated for ~15 years on primarly 87 or 89 now sitting at 145K and trouble-free. If I was towing or living in the mountains, sure, would run 93 (we don't even have 91 here in VA)..but to bee-bop around town? I'll save the $1/gallon.

Not a bit of trouble with by 2019 GTI only normal oil and oil filter changes plus a brake flush last year, always run Shell 93 octane from first fill up.
and at a whopping 8.5 K miles.

Because you understand that the world is not made up of absolutes and that .0001 does not mean success and .0002 means failure. So many forum members (not just here but all other cars) seem to think in concrete terms for everything (oil, gas, spark plugs, tire pressure, you name it) and that if you deviate just a tiny bit from the manufacturer's specifications your car will blow up. Clearly not true.

Someone above (or in another thread) mentioned "these are performance cars and need to be treated as such" but there's no rule that says a "performance" car needs to run at 10,000 RPM every time, every day forever. Some of us just use a car as a car. A fun car when you want it to be for sure but, generally, just a car. 87 octane, OEM plugs, regular steel rotors, non-ceramic pads, etc. Not gonna kill it.

I run 87 in general in my R because I'm cheap, I only go 6 miles a day, I don't floor it everywhere under load to produce lugging and pinging and I'm pretty sure my car will last a long time. If it doesn't then that's on VW for producing a modern car that can't cope with mundane driving.

some people don't know the difference between an absolute and increased probability over 100,000 miles
