synthetic blend on first oil change - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

jp_r6 · 01-16-2014, 10:38 AM

I spoke to a tuner yesterday that works on a lot of Scooby's and he said to ease the brz into full/100% synthetic oil by using a synthetic blend 5w30 on the first oil change. any comments?

The BRZ comes with Idemitsu 0W-20 "synthetic" from the factory. It has additional levels of ZDDP compared to the dealer Idemitsu oil, which I presume is to help with break-in.

Switching to a blend first used to be recommended for Subaru's (by some people) when they came with "conventional" oil from the factory, but it doesn't make sense to switch from "synthetic" to "synthetic blend" and back to "synthetic".

And stick with the viscosity recommended in your manual, unless you can show that 0W-20 doesn't work in your application (via used oil analysis, oil pressure not sufficient, etc.).

Please let us know what tuner this is. I'd like to avoid him.

He probably also has some advice on how to properly maintain the BRZ's AWD system.

My advice to you would be to find a different tuner. As for oil I would definitely use 0W-20 synthetic, which shouldn't be hard to find since I'm pretty sure all 0W-20 oils are synthetic. As for which 0W-20 to use, I'm not touching that one with a 10' pole. Lol.

There have been a bunch of very strange threads as of late by members with little to no previous posts that well let's just say sound really rediculous. If your tuner doesn't know that our cars come stock with synthetic. Run for z hills.

Ok thanks for the input guys. First This guy is not my tuner and probably never will be, I prefer to do my own tuning and what I can not do I have a excellent mechanic for that. I did change my oil and stayed with synthetic since it just sounded odd to use a blended oil in such a modern engine. My question was only because this is my first Boxer motor and I normally never sell a car case in point my 07 Tahoe has 170 000 miles on and still running strong, so I want the same for my BRZ. Thank you again.

SO FOR ALL THE NEW OWNER - STAY WITH THE FACTORY OIL STOP QUESTIONING, JUST READ YOUR MANUAL

Must think all boxer engines are the same. That'd work for an EJ, not for the FA.
