The Best Fluids For Your BRZ FRS or 86

[@angelturnhere8664]

I just serviced my transmission with the Redline sauce!Does feel smooth during shifting

[@Alexander-sr5fg]

You're going to notice the disparity between them when you heat that fluid up. Your next autocross will make the new fluid stand out. When I get it hot, the stock fluid gets notchy and feels like it binds up. New fluid gets smoother as you heat it up

[@ugrin72]

I’m about to buy a BRZ and as far as smooth shifting plus the transmission oil people were replacing both gear shift springs with more stiff and there was significant difference everyone said. Thanks for your videos

[@ImpennStudios]

Sweet , thank you Justin 😎 can’t wait to change the transmission oil as well , that’s gonna be fun

[@Borp56]

I’ve always done my differential flushes and trans changes with Subaru’s 75w90 (Keep in mind this is 2 WRXs and one 2.5RS Coupe) I’m just a firm believer that Subaru knew what they were doing so I use their products, also Subaru OEM oil filters for life! No dissing on Motul though I’ve heard good things but I can’t justify it when the oem fluid is damn good as well.

[@grimdark2740]

I can not recommend highly enough doing this from factory or used. It makes a world of difference so much so that everyone who normally rides with me noticed it.

[@pztgst]

Wow, I would have thought you had more miles on her. I have had mine for almost 14 months now and she has 11k miles, almost time for her 3rd oil change. Im looking at doing the transmission fluid with the engine oil at 12k. Thanks for the video

[@TheBTRGarage]

No problem, hope the video is helpful. Last year and a half my daily commute was 18 miles round-trip, and I would drive my truck most of the time during winter. Now I have virtually a 0 mile commute as I take public transportation into downtown for work.

[@chazmuska]

Motul is the BEST! It's ester based oil that can withstand temps much higher than other others oils without breaking down.

[@yahyashabazz5721]

Amsoil and Schaeffer's are both better

[@PainDive1]

@@yahyashabazz5721not according to friction tests I’ve seen motul protects a lot more than amsoil

[@killingtime4444]

Good to know redline is also recommended for my brz. I have that in my celica and it was night and day when i made that swap

[@Angel-HC]

I've been pretty happy with MT90. The synchros in the 13-16 boxes aren't the greatest, so it was a welcome improvement over the factory oil when I did mine. For engine oil, I've been using Mobil 1 0-40 Euro Formula. I'm told it has some of the highest film strength in the industry, which for a tightly toleranced, high performance engine is a nice thing.

[@anandbhatia780]

Absolute Fire. Im hoping to get a BRZ soon and this will be a great resource!

[@TheBTRGarage]

Great choice!

[@willieboon6150]

Your car is very clean and well maintained.

[@TheBTRGarage]

Thanks! It helps that it doesn't get driven in snow or rain all that much :)

[@slack179]

Dang. I’m at 42000 miles on my 17 BRZ now. I’m at oil change 14 right now. Already have changed my transmission and differential fluid to motel 300 at 30000. Daily driver life.

[@TheBTRGarage]

Damn, that is some driving! I do daily mine, but my daily commute is slim to none the past couple years haha.

[@slack179]

BTR Justin ya. 25 mile runs trip each day and a few road trips. Having faith that good maintenance and Subaru reliability make it last a long time

[@imjustaguy9422]

When I was researching atf for my lexus, I came across the Tacoma forums (i have the same trans) saying that Redline isn't good for sustaining high temps, and both motul and amsoil performed better

[@TripleTapHK]

They are wrong.

Back at it again with an awesome video! Well done bro 👍

[@TheBTRGarage]

Thanks appreciate it!

[@youcdtube]

Just a thought Motul makes a transmission and differential fluid for the 86, / brz

[@Carlos.Rivera]

Agreed. They worth it

[@TheBTRGarage]

Yep, they do. I have used the Motul fluid in my OS Giken differential, but that is only recommended for first 1k miles (then switch to OSG OS250R fluid).

[@alexmonzon3695]

So how long are you going to go before you change that 300V? It was my understanding that you want to change it after 3,000 miles of use since they don't contain the necessary detergents to be used as a daily driver(read 5-6k mile change interval). Thanks for the videos! They're very helpful.

[@TheBTRGarage]

5000 miles is the plan. My Blackstone analysis (of the previous oil) said to go 7000 miles. I'll see what the oil analysis looks like after that then adjust as necessary.

[@alexmonzon3695]

@@TheBTRGarage interesting! I'll be keeping up with your next change. I just changed mine today but I used motul 8100, I plan on doing Blackstone in 5k miles too. Let's compare numbers when the time comes.

[@GloveBunniesVideos]

Yay, Justin! Thanks for all your info.

[@TheBigDanois]

That's sure some fancy motor oil ya got there!😀 I constantly get asked wich oil I use. 😕 Penzoil, Royal purple or Castrol wichever is on sale that day. I mix in a quart and top up with 0w16 in winter and 5w30 in summer. Very interesting tranny oil mix. I'll certainly give it a shot.... Maybe not every 10000 miles tho😃

[@X11CHASE]

His interval was 5,000, not 10,000... he said 2nd oil change at 10k, not his first oil change. People don’t fuckin listen lol 😂

[@MsDanielm0904]

Will this same care apply to my 2014 brz? Very useful video by the way.

[@TheBTRGarage]

Yep!

[@tfpjr]

C'mon Justin...Put some miles on that Brz! 😊 My 2017 will be 2 years in March 2019 and I'm at 33k 😂

[@TheBTRGarage]

Hah, it is slow going when my daily commute is roughly 0 miles round trip these days 🤣

[@mistople]

300V FTW!

[@zimotheone7402]

Hi Justin, thanks for your videos. What is the interval change for the 300v they suggested in the shop? And what kind of use ? Next , why they suggested to mix the two redline type?

[@TheBTRGarage]

5000 mile interval is pretty normal for my type of use, autocross, occasional track, and street driving. CSG said the Red Line mix has performed better in their testing. I am not sure exactly what their testing was, but that is why I trust them so I don't have to do extensive testing on things like this :)

[@zimotheone7402]

@@TheBTRGarage thanks mate! Could you please check to oil temp because i have a brz friend(i have gt86) that use 300v 5w30 and has lower temp than me. I use motul 5w30 and i like the idea of 300v ester base oil but motul is the first to declare that is a "racing" oil so i'm little scared (my is DD and spirited driven use in summer)

[@LoveLikeaHurricane]

@@zimotheone7402 you can have the same car with the same oil, but may have diffferences in wear of oil. It is always wise to follow 3000 for severe service such as racing/autocross/track days and 5000 miles for light high way pulls and daily use. Wit a racing oil, despite what oil analysis might indicate, it is not wise to drive it with high miles on it as it was not designed for that intention. Learn from your proven high performance cars such as Evos, s2000, etc on there types of oils and usual oil change intervals for their use.

[@ESHABAMBOO]

Has anyone else tried this combo? If so, how was it? Upgrading my clutch and might use this combo only because I can’t get my hands on Motul in time.

[@TheBTRGarage]

This combo was/is recommended by CounterSpace Garage. I would recommend reaching out to them if you have detailed questions, they usually have good data and detail around why they recommend certain things.

[@Slanovich]

Did you mix both Redline oils for the differential too, or only use one?

[@TheBTRGarage]

No, not for the differential.

[@Slanovich]

@@TheBTRGarage Thanks. In that case I might just go with Motul for the simplicity of using the same oil in both the trans and diff with less waste.

[@bubucachoo0882]

Royal purple 75W90 gear oil ??? Anyone try it in any automatic brz/fed/86??? For a transmission oil change?

[@richj3168]

Hey Justin. People are saying that Royal Purple gunks up the engines in the Twins. Even had a subaru dealership mechanic tell me not to use it. You think it's BS? Thanks for the video!

[@TheBTRGarage]

I've never had any problems personally. I just got the Blackstone labs test back that has the results for the 5k miles on Royal Purple, everything looked just fine for whatever that is worth.

[@richj3168]

@@TheBTRGarage Oh cool! Glad to hear you got the results back already.

[@K03sport]

Disagree, AGIP's Hello Kitty oil is better (ask me how I know) and it's only available in Japan 🇯🇵. 10k for a trans service seems premature, especially if the car doesn't see daily/winter duty, unless the OE fluid is just mediocre; but it is relatively easy to do and not that expensive.

[@mitsu1132]

Motul oil is okay to use for daily right?

[@TheBTRGarage]

Yes, of course. Although it might be on the expensive side compared to something like Mobil 1 synthetic, which is another option.

[@teresaortiz3316]

Hi I just got my frs I’m noticing a clicking noise when I cut the wheels do you know what it could be ?

Hi, can I ask where you bought those lifts?

I bought them through the QuickJack website, but many places sell them. If you search for my QuickJack setup video I also have links.

[@Mattouge]

Nice video. And nice T-shirt lol

[@TheBTRGarage]

Haha, thanks!

[@mattsticrazy]

How much fluid did it take to fill the transmission?

[@stephenmac23]

Is this recommendation for autos as well?

[@TheBTRGarage]

For the engine oil yes. For the auto transmission, I would stick with OEM fluids or get guidance from CSG on transmission fluid.

[@jbrockskill]

I've heard many prefer 5w30 than 0w20 what's your take Justin?

[@TheBTRGarage]

I think for most use cases the 0w20 is going to be just fine, especially if you live in colder climates. From what I know, 5w30 is going to be more beneficial if your car is seeing a lot of track duty. During extended track sessions the oil gets hotter, and therefore thinner, so having a slightly thicker oil would lubricate better and still be within its working range, compared to the thinner to begin 0w20. This is why I asked CSG what their recommendation was for my use case, so I knew I got the right stuff :)

[@gt86dude16]

To add the BTR Justin's reply. 0W20 is what the engine is designed for. If you have a temperature issue (on track or otherwise), don't bandage it with running a wrong specification oil. Fix the temperature issue instead by installing an oil cooler.

[@jbrockskill]

@@gt86dude16 Well I live in texas where it gets into the 40's at coldest so I thought the 0w20 seemed kinda pointless for my temps here, it might help fuel economy being so thin. I've ran Pennzoil 5w30 for roughly 40,000 miles(car has 53,000 currently and was bought new) and no issues. But yep oil coolers are great for places like mine.

[@gt86dude16]

@@jbrockskill 5W30 is approved for the engine. But you would be surprised what people put into these engines (e.g. 20W60, eek). 40 deg is pretty cold when cold starting the engine. I rarely drive my 86 at lower temps either. I would still use 0W20 and manage the maximum oil temp with an oil cooler to stay below 240 f when tracking. Also, if tracking or driving hard decrease oil change intervals to max 4000 miles.

[@thegroundhurts]

I notice oil pump cavitation over 5800 RPM with 5w30. Pressure builds to over 70 then drops to 58 or so at redline. Oil temp around 220-250. I went back to 0-20 and it is not as bad but still starts to drop pressure on the top end.

[@pbd6488]

I use amsoil

[@martnomb879]

Rear diff are the same? Secret sauce?

[@TheBTRGarage]

No just the prescribed diff fluid.

[@stone10473]

What oil do you recommend for the stock BRZ rear diff?

[@TheBTRGarage]

I like the Red Line 75w90ns for the differential.

[@stone10473]

@@TheBTRGarage What's the reason for mixing the two redline fluids for the transmission?

[@TheGoodMedicine]

I think you have received false info, that mix was for the diff not your trans. Did you fill 6 liters of oil in your engine?

You're welcome to call up Counterspace Garage and tell them that.

[@TripleTapHK]

100% for the trans.

[@godlymonstersstudios486]

Hi Justin , thank you for your videos (: very helpful but I just realized my BRZ is an automatic , and I was gonna use the same one for my BRZ but is it same oil for the automatic BRZ ? Or diff oil

[@TheBTRGarage]

The diff fluid is fine, but you probably want a different fluid for the auto transmission. I would reach out to your dealer or a shop like CounterSpace Garage for recommendations.

[@godlymonstersstudios486]

@@TheBTRGarage thank you Justin , I appreciate it :)

[@midnighteightsix6919]

You should have just put MT-90 in the transmission, NEVER put a GL-5 rated oil like the 75W90NS in an 86/BRZ gearbox. Any GL5 rated oil has too much sulfur and phosphorous for the brass/bronze synchros and will eat away at them over time. Eventually the synchros will become weakened and fail prematurely. The same goes for the Moutl gear 300 oil with a dual GL4/5 rating; anything with a GL5 designation of any sort is too strong for our gearboxes. The service manual calls for a GL3 in the transmission, Toyota/Subaru mention nothing about putting GL5 in. Why anyone is recommending to go 2 ratings higher is beyond me. Caveat emptor.

[@TheBTRGarage]

GL-5 oil is pretty common for the transmission. Even OEM Subaru GL-5 75W90 : www.ft86speedfactory.com/subaru-75w90-high-performance-gear-oil-1825.html www.redlineoil.com/75w90-ns-gl-5-gear-oil

[@TripleTapHK]

@@TheBTRGarage Exactly. Everyone swears by the Motul gear oil for these cars as well and it has GL-5 in it. I assume counterspace is mixing the 2 redline oils because the NS stuff is good for syncros but is GL-5 so they mix it with the GL-4 oil since it's better for the types of gears that manual transmissions use.
