Need Oil change recommendation
 

Hello! my 3K service is coming up in a couple hundred miles and i was wondering what people could recommend me as far as the oil change! Leaning towards the Motul Gear 300 but i dont know if i need to buy anything extra or i can just get the oil and take it to the dealer to have them change it.

there is no 3k service. 6k for 2015's, 7,500 for years before.
Many people do the trans/diff early and find lots of debris on the magnetic drain plugs. I plan to do mine at 6k for my 2015. I am going to use motul also.
Read your manual.

Read this.

Also, although Motul is reportedly great oil, Toyota OEM oil is very hard to beat (read the endless threads on this forum).

First Motul 300 usually refers to Gear and Diffy fluid.

There are a few items:

Motul Gear 300 75w90- good to put in around 3-5K miles in the Trans and Diffy
Motul 8100 0w20- good engine oil and would suggest changing at 3K miles and then every 5K miles after that.
Motul 300v- racing oil that I wouldn't suggest being used in a street car unless you track it and if you do track it and street drive it then change it every 2k-3k miles due to a lower detergent/additive package.

For a street driven car, standard Toyota or Subaru engine oil every 6-7.5K per owners manual.

Driveline oils should only really be done to sort out shifting issues, why fix what isn't broken. For a street car a 20K mile trans/diff oil change interval would be a nice aggressive preventative maintenance schedule.

For a track car, do whatever makes you feel comfortable and change fluids often.

my service for 2015 is 7.5k?

Should be 6k for 2015 model years. Mine is anyways. Maybe your manual would say.

i use MOBIL 1 and ITS GREAT!

300V 0W-20 - additive pack strong enough for 10k?

;)

There's also a voa in that thread.

Wouldn't be surprise as there's a member here that ran the oem subaru 0w-20 for 10k+ and blackstones oil analysis report came back great.

I am basing that off of extensive emails that I have had as a dealer with Motuls engineering department. It is in my best interest to sell 300v over 8100 as it is more expensive and higher profit margin. Unfortunately if the manufacturers engineering dept tells me the product isn't appropriate for street use due to the additive package not being setup for street cars I will continue to promote that as a pretty good reason not to run it on a regular basis.

Point taken. It's probably a CYA move since uoa's with track time show that any grade 300V can handle 6-8k miles oci's with no problem.

Similar to the CYA move by Amsoil advising to stick with SoA's oil change interval recommendation on all turbocharged Subaru's after a knucklehead Legacy GT owner ran a 25k mile OCI as advised by his knucklehead Amsoil dealer. :D

Entirely possible. I run the 300v in our track car that was routinely seeing close to 300f oil temps during 30 min sessions the UOI came back without an issue. However we have lots and lots of 8100 series UOIs from our own testing and customers that at 5k mile OCI there is no discernible difference between the 300v and 8100 at 2x the cost.

So 8100 for a street car that sees the occasional track weekend or auto-x would be just fine? (This is assuming the use of an oil cooler.)
