Well to be honest, so far I've heard from all good mechanics saying oil changes should be done at least twice as often as the manufacturer recommends for all cars, no matter the brand

To answer the original poster's question (I can at least try to be constructive): Flat Subi engines have higher crankcase pressures due to a smaller volume. This means they tend to suffer more blow-by and burn more oil, and they desperately need their PCV system to be maintained religiously every 30k miles or so due to the pressures in the crank. This is not a design flaw, it's inherent in the layout. As Ezekiel said, you need to be religious about both routine maintenance and oil/coolant levels. If either gets too low, you can starve the engine of oil/coolant and then you have no more engine. Subi engines tend to burn oil while also being more sensitive to blowing up if they don't get enough oil. Boxer engines generally have two head gaskets and two valve trains, not just one of either, and this makes them doubly susceptible to anything going wrong with these just because there are two. Also they don't deal with thermal expansion as well by default because there's just a lot more surface area, across which things heat up at different rates. So it's a lot harder to build them and get them dialed in correctly. Rebuilding them is harder for this reason, and more expensive and error-prone. The positives are low center of gravity, and no need for a balance shaft to tame noise/vibration.
Dumb dumb question here. My coolant level is always low when the car is off and goes up near full when the engine is hot after I’ve been driving. So do you check coolant level when the engine is hot or cold??
@@CMAutohaus nice thanks for the helpful reply! It’s been like this since I got the car from the dealer so I’ve never been concerned about it but I’ll have to top it off now that I know this. Do you recommend Subaru blue coolant or something aftermarket you’ve found to work better??
If the coolant overflow bottle is FULL level when the engine is cold - that means it expels out on to the ground when you drive it because heat expands......they told me if i check the coolant when the engine is cold the level should be at the L level or slightly above the L level on the plastic overflow bottle. @@CMAutohaus

Thank you for the great advice. I have a question regarding checking the dipstick for my 2023 GR86. Should I exam it on a cold or hot engine? I recently got an oil change at my local dealership and on cold it's slightly above the first dot. When it's warmed up its just a bit over the second dot. Sorry if it's a dumb question.
Check both sides of the dipstick, lowest reading is the correct one. If you just ran the car, wait 30mins to check the reading - first start after an oil change, the reading is always incorrect - approx 1/2 qt low
Wait what. I might have filled my oil a tad under the dot. Because one side of the dip stick always has it touching the dot while the other is always below slightly. Am I fucked. I drive hours on hours every day, hella stressed out on this now lol
@@NightKidBrandon Leave it. That is correct. One side will ready super high, and the other side is the correct reading. A tad over the dot will NOT hurt anything
@@CMAutohaus thanks for always replying! U are my #1 trusted source when it comes to the new fa24. Do you have an opinion on 1k mile oil change? I’ve reserved researched the topic fully but would like to hear your thoughts
@@NightKidBrandon I recommend it for all enthusiast vehicles. We've done the 1,000 break in fluid services to the new WRX and GR Corolla and the fluids/filters always have lots of break in material.
The manual says 5w30 is acceptable as well for fa24 in gr86, would you agree? Live in Sweden so -15c winter time and +20 in the summers, drive somewhat harshly when the engine warms up

I was a mechanic and you are 100% correct.
Especially on the subaru sti
Great videos
Keep posting them!!!
Will do! And thank you for the watch and support!
Good stuff. Thanks 😊
You mentioned the Boxer Engines have quarks, could you provide a list of "quark examples"?
It’s “quirks” bro. Quarks are a subatomic particle

Check the coolant over flow when cold. Should be at FULL level

Dang, i went to put .1/.2 more and now one side reads super high and the other side is a tad over the dot 🧐🥲 how tf do you read these darn dipsticks 😖
@@NightKidBrandon Leave it. That is correct. One side will ready super high, and the other side is the correct reading. A tad over the dot will NOT hurt anything
Pistons laying sideways. More wear on piston rings due to gravity
Also, are you sure u meant to say hair under full? We’re talking about a .2/.1 quart deficit!?! I’m so paranoid now!
.2 qt over or under really shouldnt hurt anything
@@CMAutohaus what about .5 under
@@NightKidBrandon I'd keep the engine oil and coolant at the full level at all times.

What type of oil do I use for 2023 GR86?
0w20 any premium sythentic brand is fine
