It's always an interesting debate with strong opinions. Some issues in the WRX/STi market have proven to be addressed (assumed for the better, with little-to-no data to back it up) and some have done side-by side assembly comparisons showing the changes and different part numbers. You can see it through the progression of EJ25 blocks stamped 701-706 now being the most recent and arguably, the most reliable and capable. No idea if there has been that same progression on the FA20. Not one that I can remember from our research when were involved with the FA20 WRX from 2014-2017. The major thing I remember is the FA20 BRZ and WRX blocks were different, even though they are both FA20. Found this out the hard way when sleeving an FA20 BRZ block; the sleeve company gave us FA20 WRX specs for machining and install, assuming BRZ and WRX blocks were the same |

I'll try to dig around when I have some downtime. I'm curious because the opinions are counter to our experiences on several platforms... but if it means fewer oil changes without compromising the quality and condition of the oil, I'm all for it!

Is it really staggering or is it just we only hear about those and not the vast majority that have lived uneventful lives? I think it's the latter personally.

I have followed each and every failure reported on this forum since 2014. In fact I even had a spread sheet for a bit. The number of catastrophic failures for all reasons is tiny compared to the sales numbers. This includes the recall debacle. I gave up on the spread sheet a long time ago as there were so few it was a waste of time. I would say that since 2014 there have been maybe, just maybe a maximum of 200 failures reported here. Now people will say "but Tcoat you are an idiot since 200 is a lot". Since the car was released there have been almost 100,000 of them sold (FRS/86/ BRZ combined) if the number of failures was truly "staggering" as people claim the should have been several thousand reported on here. Even if we take the number to a pulled from the ass whopping 2,000 catastrophic failures we are still at the 2% mark. The real number is probably sub 1% though. This is on par with any other car out there and better than some.

With that said most non design-flaw problems are due to mods and people pushing motors to deal with more than the stock specifications. A side effect of this is that its weaknesses usually get found that the stock specifications wont really encounter |

There is also an E85 thread that has quite a few UOA's on it IIRC.

From a sample of 1, mine is still running fine.
Even all the switches and levers still work.

The big topic was always the EJ Oil Pickup failures, which is often catastrophic, and how common is it really? We obviously hear loudly on forums and social media from the enthusiasts. What we don't hear is about the non-enthusiasts car guys. The guy that loves driving these cars, but take it to the dealer for every inspection, oil change, tire rotation, blown parking light bulb, etc... Heck, as much as I want my kids to be 'enthusiasts' they fit into this category of loving the driving experience (going to Auto-X, rally, cruises, etc.) but want nothing to do with getting dirty. It makes no sense to me, but who am I to judge. I sometimes see these people at Auto-x and track events, and when they want to go faster or handle better, they go to a shop and get recommendations and have it installed. Still strange, right? lol Anyway, this 'other' group is not insignificant. Unfortunately, as much as I've asked, I can't get any data from any dealers in regard to how often a car has failure or issue X, Y, or Z. I get 'yeah we see that happen', but little else. Understandable considering what repercussions that could have. My point is, assuming is not reality. MY assumption as that there is even a bigger demographic that fits neither of these. They enjoy the cars, but not beyond their 'normal' lives and routines. Go to independent shops for service and Jiffy Lube for oil changes. I know, cringe worthy, but maybe true? No, but I'm assuming all DI setups are not the same aside from the premise of operation. The 911 and AMG guys are pretty fanatical about E85 oil changes, and I've seen UOAs that support that. Also, easy to search out if you dig through the forums. We definitely saw fuel dilution on our shop mule 911 on E85, but we didn't run it often enough to where I saw conclusive data, and it was used primarily for product testing on the dyno. I follow some RS3 groups, and I know E85 is popular there too, but I've not followed closely enough. Fuel dilution is not just due to the fuel type, but the A/F mixture, ring pack, piston material, PCV design (those other cars have an AOS from the factory), piston-to-wall clearance, etc. so there is certainly opportunity for some engines to be less prone to dilution than others, which is why I'm keeping an open mind about it. |

ND’s blow up transmissions with pretty low miles, not sure if there’s a fix.
FA20’s seem to have engine oiling issues, oil cooler, pickup upgrade and baffling help. Pick you poison. Personally I’d take the Miata if I could live with its lack of practicality, but I can’t so 86 it is for the time being. |

Tell a European consumer he needs to change his oil every 9k and he'll tell you that's far too often and he can't be bothered. Tell the same to an American driver and he'll be scared for his engine. Then again, I think those cars can be called reliable by either standard. Random catastrophic engine failures seem few and far between. Most don't seem that random at all and involve some type of repeated engine abuse or bad maintenance. Not sure about the money shifting part though, you'd really have to try to misshift an 86 it into second, as the synchros would likely want to have a word with you first. There's a few nibbles about these car's reliability, but if those are enough to scare a fella off, he / she should stick to bicycles |

I've only known two people IRL that have killed an engine in any road-going car, and both cars were Nissans.
My brother didn't know he had to change the oil in his 3 years of Altima ownership, until it died. My father forgot to change the oil in his Pathfinder for like 2 years, then it died. Yes, I am related to these people... Moral of the story, my experience says you are very likely to kill the engine by not changing the oil, or driving a Nissan. Otherwise it is probably fine.
