^^^ I wouldn't just because i choose to shorten my intervals to 5k does not mean im not going to use top shelf oil for my car, in this case ive been with Motul designed for DI motors and use OEM Filter...
I dont see why sacrificing "potential" oil quality just because you shorten intervals makes sense? To me it would be the same as using good oil for the full 10K to shorten inverals and use cheaper oil..
In the realm of things its like ~70 bucks an oil change...if you're driving a GTI, I dont think it should really be hurting your wallet for some good piece of mind?
To me this is a cheaper oil change then the other cars ive owned so maybe im biased in that sense?
I agree, if your going to use crap oil you might as well just use good oil and go 10k.
I think it only cost me about $55 bucks including filter to change it, which is worth it to me.
