There's no evidence to the contrary, but there is evidence that motors run fine with synthetics today with 220+ temps, all day long, in the heat, for years. I know the track only Porsche guys see 280+ and usually swap out the piston rings for good measure after the season is over, but this is purely PMI. But we're not talking 280+ Running an oil cooler is fine, I run one for good measure (PMI). It's definitely not necessary for everyday driving/autox.

i ran my turbo without an oil cooler for a year in florida with no ill effects. i have one now, but only because i found a great deal locally on one.
i agree it's a good idea, but it's certainly not a 'must have or your car is doomed' type of thing like some suggest. modern synthetics don't even begin to degrade until well above the temps that i ever saw in the summer with the turbo and no cooler. if you talking about 30 minute track sessions that's a whole different story, but then in that case you'd want one on any car, FI or not. |

The OIL itself can handle the temperature agreed, it's the engine /turbo that can't. This is a non-FI engine already producing quite a bit of heat, throw in FI and multiple pulls in the heat, the long term affects on seals, head gasket, internals, etc. will be not good, trust me (coming from a guy who has blown a few engines racing ) Last edited by Jason@DSG; 05-21-2014 at 05:06 PM. |

Honestly, I got an oil cooler primarily because of Dyno results showing that after 230 F, the ECU starts pulling timing.
OR more accurately, that is what Perrin dyno results showed.

I'd also be willing to bet that oil breaks down before metal, I'm no scientist but seems legit. I also don't trust people that have off-hand wild comments followed by "trust me" (and the fact that I actually don't know you).

Have you or James ever seen that in an EcuTek log? I remember hitting 260Fs after 4 or 5 third gear pulls, haha.

racing breaks things. we all get that... but we're not racing. again i'm not saying it's not a good idea in any case... FI, NA, street, track whatever. I'm just saying that there is more alarmism than realism on these forums when it comes to what is actually 'required' vs. what is a 'good idea'. |

I have a few logs I can check out from another car, but have never reached 230 on my car yet after radiator/oil cooler.

To reiterate...you're all missing the point. It's NOT about oil degradation, it's about the internals of this engine under those temperatures long term.
Why do you think the following Turbo cars come standard with oil coolers: EvoX, GTR, STi, etc. It's not the actual oil that's the concern but to each their own. We'll follow up this convo for guys going FI after 5 years of ''spirited driving'' and tracking with 220+ oil temps on a regular basis.

Remind me not to ever log and research anything here, seems like some of you guys are extremely unappreciated.
Chris is just trying to keep the car safe and you guys are just shitting all over him. Regardless if 220F is "normal temp" i rather have my temps run lower. |

Like I said, to each their own but if you put FI on this car and think that 220-250f oil temperatures are okay, then power to you but that's just loco! |

And people also don't get that yes, short term it's not an issue but a non-factory turbo charged car that has no turbo cooling/oil cooling is a ticking time bomb.
