I purchased an eight-six, or more specifically a Subaru BRZ, last year. Subaru recommends 0W-20 for street cars. I do however drive the car like I stole it. After the breakin period I changed the factory fill to Red Line 5w30 at 2k miles. Even after prolonged flogging, I do not see excessive oil temperatures. What oils do you eight-six owners use?

It does however mean that if he had an oil related engine failure that they could deny warranty coverage. It does not completely invalidate his warranty.
Impact on MPG will be very slight. If the vehicle is flogged (which it was noted to be) then MPG impact will be essentially non-existent.

If it gets driven hard then you probably did the right thing by moving to a 30 in my opinion. It will not cause excessive wear but quite the opposite.
I think 5w30 is whats recommended for them over here and many people will no doubt use 5w40 in them too if they get tracked or driven hard

Where does the supposed excessive wear come from? If oil flow were to suffer due to the higher viscosity oil, then surely the oil temperature would climb. Don't care about warranty or gas mileage.

People who track the eight-six commonly use 5W-50. Haven't heard of any issues due to lubrication failure.

It's a sporty car and Toyota/Subaru understand it will be driven hard. Unless you constantly track the car in SCCA type events, i'd stick with the OEM recommended 0w-20.

Which eight-six do you own and do you drive it hard?

Which eight-six do you own and do you drive it hard?
Neither. Nor do some of the other posters you'll be receiving recommendations from. But i do know Toyota also recommends TGMO 0w-20 for their new Lexus NX 200T. If you're strictly looking for other owners of the make, give one of the FRS/BRZ forums a try as well. They will know the vehicle better than most here.
Now, do i drive hard? Well, as a former EVO VIII, WRX and NismoZ owner...

I think even a 20wt would be fine with the most extreme driver behind the wheel. I use a 20wt in my truck and it gets revved and driven very hard. my car gets the reccomended 5w30 but it also gets driven hard when I drive it. multiple full throttle redline pulls and high speed on the highway. The used oil analysis always look the same and it runs like a top. I'd go with the tgmo in a 0w20.

I'm coming from the FRS/BRZ forums, but I wanted input from the oil gurus, or rather from those oil gurus who have an 86. Nothing beats first-hand experience. Probably my mistake to expect too much.

An engine's ability to heat the oil is directly related to power density and sump capacity; how much heat it can generate and how much of a sink exists to take that heat. Your truck has a relatively low power density and good sized sump, ergo, even driving it like a maniac, you are likely unable to heat the oil as much as the OP's engine, which would have a higher relative power density and probably a smaller sump.
That's not to say the OEM recommended oil isn't adequate for the application, I'm sure it is. Simply that each application is different and that there are individual considerations that can come into play. If he was tracking the car and noticed elevated oil temperatures frequently, a heavier oil may be beneficial under those circumstances.
I'm not advocating he continue to run a heavier that spec'd lubricant in this application, but it certainly isn't going to cause any damage either if that's the route he wants to continue to take.

In my BRZ I change the oil every 15000-16000 km. After the initial break-in I used a 5w30 for the past 30000. I am going to switch to a 0W-20 soon to see if I can save any fuel. This will be my 3-d oil change. When I switched to a 5w30 last time the only difference I could feel was a slightly reduced idle noise. If the fuel consumption difference is not detectable I will switch back to 5w30 because there should be an economical reason to use a thin oil. Otherwise the thicker the oil the better I feel.
A 0W-20 is not required for the BRZ. It is recommended with an option to go higher for heavy loads. Though, they don't mention how much higher.

good point. I didn't think of that. im kinda a thin oil fanboy. All the best oils are 30wt and under. Well up here at least. I would love to see some lab data from a thick and thin full out test.

People who track the eight-six commonly use 5W-50. Haven't heard of any issues due to lubrication failure.
Yep most people here who track them (or any other car) use Penrite HPR-10 which is 10w50. I doubt it has ever caused a problem in any engine

Sustina 0w20 is very popular in this motor and used oil analysis have shown it's a great fit. It's expensive, but arguably the ideal oil for the motor and OCI's can be extended to make up for the cost a bit.
