I recently had an oil cooler installed and it has reduced oil temps, but I wonder if I used a dual oil cooler set-up a-la porsche etc would I be able to reduce temps even more. I just want extra piece of mind because my TT set-up is like an oven!!

 

Why not? It's been done before, check out XKR's build.

 

Yes.

/thread .

 

this is interesting .. and word man, it gets hot under the hood! Currently looking into using the NISMO hood ventilation template someone was cool enough to post hoping that will get rid of some trapped heat!

do you even have a oil temp gauge? Colder doesnt = better

 

I have one on the A-pillar. My hi temps are +220. I would like the temp to stay between 180 & 190.

 

220 is still normal operating oil temp imo

 

just get one big *** oil cooler like GTM's competition kit. i hit 230's in the texas summer heat just cruising on the freeway.

 

Hmmmmm.

 

interesting

 

I too was under the impression that once you abused the oil running the car and pushing it above the 240 temp range,(i.e. a track day) it would be advisable to replace the oil because the viscosity protection it offered was shot.
Maybe I'm wrong. I'm sure someone here will enlighten me.

 

^^ Point well taken & well said!! These are the kinds of issues I am considering.

 

Use a good synthetic. I still don't think 220 is anything to worry about and 240 is not going to ruin a synthetic's viscosity protection imho. 260+ and I would start to worry. I'm sure there will be those that disagree with me and everyone has their opinion. You don't need your oil to be at 180. 190-220 is normal operating temps imo.

 

220 peak on an fi car in the middle of summer is perfectly normal particularly on a built motor

 

Normal operating oil temp, cruising in the summer for me is 220-230, with a decent sized B&M oil cooler. In ambient temps of 100 degF, I can pass 250 in just a couple mins with a combo of boosting and revving on the twisties...

Randy, I think you're spot on, but the rate of additive degradation is an unknown. I would hope that if you change the oil every 3k miles, you can push into the upper 200s. I personally never let the temp go higher than 260. If I set my limit at 240, that would be like only 10 seconds of fun.

 

i feel much better about my oil temps after reading everyone's comments. with a mocal t-stat sammich plate & 16 row earl's cooler, i see the following temps:
- 70F day, highway cruising: 185-195F
- 70F day, sitting in traffic: 210-215F (after 20-30 mins, which happens all too often here)
- 95F day, highway cruising: 210F-215F (on way to Vegas)
- 95F day, sitting in traffic: why bother???

oil is mobil 1 0w-40. i guess it helps that my blower doesn't run off engine oil like some of you guys' turbos do

 

Just wondering but did u say you sit in traffic for 20-30mins at a time?!?!?!

 

unfortunately yes. san francisco is like 7 miles wide, but it can take me 20-30 mins to get to the nearest freeway

 

Randy - As I learned the hard way, and was explained to me by my tuner, the oil may be able to take the temps, but the parts may not

I am still considering a dual cooler setup in a daisy chain fashion. As long as its t-stat controlled it shouldn't be an issue in the winter. This, of course, assumes that my car ever gets back to one piece and leaves the garage again

 

220 peak is not bad at all.

you'll never get temps to 180-190 peak when you're boosting. Think about how hot that oil is returning from the 1200* turbo.

where do you have your temp gauge? I have mine right in the side port of my greddy pan. I see 220 max if i'm doing some hard driving. On the highway it cruises at 180's in 90* weather.

I can't find it now but if you search how they test oil they test it well past 240 degrees. Like someone just stated the high temps hurt other parts more than the oil but 220 isn't high temps.
