I'm on Eneos 0w-50 right now.

 

When some of you guys decide to switch from a 50 to a 20, make sure you monitor the load cells your car hits. Some of them will change...

 

i like you, you get it quick

ATM 10W30 flashes at 439 F, and it pours at -54 F

RD 10W30 flashes at 453 F, and it pours at -44 F

SSO 0W30 flashes at 446 F, and pours at -60 F

 

Good info thanks for sharing.

 

people on the fp reds in the 500 hp territory ?? what r u using

 

I like Amsoil SSO 0w-30 or HDD 5w-30 for fall through spring. In the summer I will run AMO 10w-40

Mobil 1 10W-30 currently
getting ready to switch over to AMSOIL

 

stock turbo 320whp 10w30 all year

 

Did that answer your question???

 

As promised here are the results of the SSO 0W30 in my S14...I know this is an Evo forum and I will post those results in the near future.

The car consumes about 1-1.5 qts per 3,000 mile interval; however, I think most of that is actually leaking via the front and rear main seals and possibly the oil pan. I have been running Amsoil Signature Series 0W30 for a full year now. I was mostly concerned about the strong fuel smell when I checked the dipstick. Results seem pretty good overall.

At the the time the oil sample was taken I did a compression test that surprisingly yielded 190 dead even on all 4 cylinders. It was done using an old AutoZone-type compression tester with a baterry charger hooked up, fuel pump relay was unpluged, throttle was at 100%, and the car was turned over about 5 times.

The car has not been autocrossed, raced, or abused really since I have owned it for nearly 2 years ops: However, I do the ocassional pull on the highway and take full advantage of every on/off ramp. Otherwise, the car spends most of it's days parked.

Their comment on not bringing the oil up to temp is actually unfounded as I drove the car on the highway for about 40 minutes prior to taking the sample. I think the fuel dilution is due to the overly rich tune of the ECU. I don't think there's a leaky injector...and all the plugs looked even when I changed them as well.

Relevant mods:
- stock 170,000 miles short block
- stock 50,000 miles head
- 248/248 S13 cams
- Leone custom tubular exhaust manifold
- 50 trim w/.63 ar at 12psi
- 550 RX7 injectors
- S13 Enthalpy ECU w/adapter harness
- all other supporting mods

 

Oberon 15W60 + 850R

 

That is some thick A$$ oil!!!

 

thats due to extra hot climate conditions where i live.
during summer the average temperature is 116F.

 

Very good report, and very nice for a high milleage motor.

that SSO is doing its job at maintaining the TBN super high even when you are fuel diluting it.

 

I'm currently running 15w-50 RD Amsoil and thinking about switching down to a 5w-50 (not sure what brand) synthetic, but not sure if there is a real benefit or worth switching due to the very cold temps we are seeing up here in NY. What do the oil gurus advise?
