0W-16 Oil - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

FR-S2GT86 · 08-28-2020, 01:50 PM

Has anyone with forced induction tried this new 0W-16 oil developed specifically for boosted, direct injected engines in any of their cars yet?

I'm suspecting it may not work quite right with the VVT system in the FA20/4U-GSE and may cause some codes to start appearing concerning the cam timings.

Why would anyone ever dream of going DOWN in oil weight from the already light weight 0W20?

That wonderful cold start protection!

Honda is beginning to recommend it for their turbocharged engines to combat the oil dilution problems they have been having.

I asked Bubba about 0W-16 weight oil and he says you might as well put kerosene in the crankcase.

Might not be a bad idea of those of us seeing winter conditions. Those -20 cold starts.

I imagine those engines are specifically engineered to run 0W-16. The FA20 isn't. Using thinner oil than what is recommended by the manufacturer is almost universally a bad idea.

I doubt 4 points would make a difference in a cold start. Not worth the trade-off with risk, since pressure is really important on cold starts where everything is drying out

Halo_2 · 08-28-2020, 10:29 PM

They are both 0 it would make zero difference in cold start......

Hold on a sec. Did I read you correctly? Honda are recommending 0-16 to COMBAT oil dilution? So their thinking is adding gasoline to a 0-16 will transform it into a 0-20?

Manufactures want thin oil for better fuel economy. That's all.

I went 5w30 when I added forced induction because all Subaru engines that are forced induction come with 5w30.

If I was tracking the car then I would consider an oil cooler and a heavier grade oil. The GT86Cup manual has the oil listed as ELF HTX 825 10W60. There is an oil cooler option. This is for "stock" cars, so no forced induction, which means less heat and less forces pushing down on those bearings.

Seems like an oxymoron to go thinner to combat dilution.
Is their reasoning that it’s already as thin as gasoline, so adding more of the same can’t hurt?

To make myself more clear, though I was mostly joking, it does make a difference. 0W-20 will have a lower viscosity than a 0W-40 oil at startup. In the case of 0W-16 vs 0W-20, the difference is probably quite insignificant to care about, which is why I intended it to be a joke.

As far as I understand, 0w-40 will still have lower viscosity at startup than 5w-30? I wonder why most people do 5w-30 and 0w-40 is rarely mentioned.
