I'd have to agree and
I'd have to agree and disagree with you to some extent. Being and owner of a turbo engine vehicle which is a 2015 Lincoln MKC 2.0 AWD. Sure i can drive it around with 87 octane just fine. But you better believe i take a hit on torque using that low grade fuel on the highway and when i need to merge. And the same would apply for most any turbo engine. They are capable of taking regular gas but if you bought a turbo engine and want ALL of it's available torque then you should be using premium or at the very least mid grade fuel. Now you can compensate for this by using low grade fuel and adding in an octane booster additive into your gas tank. But your still not going to see the same numbers as using premium fuel. Therefore, the 3.6r Subaru engines using regular fuel are going to out perform these new turbo engines Subaru has decided to go with in the 2020 models. When i test drove a 2.5 vs 3.6r 2017 outback limited model the difference was quite literally night and day. Not to mention even though Subaru sold more 2.4 engines then 3.6r engines. The 4cyl had FAR FAR more engine problems and oil leak issues opposed to the 6cyl which is pretty much bullet proof. So if i were in the market for an Outback or Legacy i would DEFINITELY go with an older model 3.6r no doubt about it just for the sake of long-term reliability.
