Once you get oil to about 110-120F I would pop it into manual and cruise in 5th or maybe even 4th (Depending on traffic/speed). It does hurt MPG a little bit, but it will warm up your oil a lot faster. you should be good to go for some pulls in 10mins or less after startup that way. at about 140-150 ill do mini partial throttle baby pulls if I want to speed it up even faster.Ok, so I took my 50 to work today. Used my JB4 to watch oil, coolant ("water"), and trans temps. 30 min commute. Mostly freeway. Did not 'get on it' at all, just conservative driving. Ambient temp was high 40s.
Oil temp painstakingly took the whole commute to slowly creep up and eventually end at high 150s. Coolant temp got up there pretty quickly and stayed there. Coolant temp was 190 when I parked my car. Trans temps never got higher than high 50s. Trans was 59^F when I parked.
Yeah....BMS was too lazy to do it right so they mislabeled trans temp and it's the charge air coolant temp.Just to clarify, JB4 "Trans Temp" is the heat exchanger/intercooler fluid temp, not the actual transmission fluid temp.
160 would be really hot for the HE coolant temps.
Interesting to know.Yeah....BMS was too lazy to do it right so they mislabeled trans temp and it's the charge air coolant temp.
Either that or tighter tolerances create better fuel efficiency but also requires a thinner oil. And the fact most people never get their oil temp over 170s on their normal daily commute would amplify the need for a thinner oil. A thicker oil won’t be able to flow well through the tight spaces and properly lubricate everything especially if it’s not fully warmed up 200F+ , Even engines built for nascar use 0w-20 or sometimes thinner.It's actually for fuel mileage to help hit Cafe standards.
Are you able to log knock?Trans temp and knock are my 2 PIDs I've wanted for a long time on the JB4. I always logged trans temp on my v8 stuff.
Nope. JB4 STILL can't log knock or transmission temps. It's so annoying.Are you able to log knock?
In the Subaru world, it is a no brainer. Not only knock but also knock learning and ignition timing multiplier...all available on Cobb accessport.
Why our platform is so far behind is beyond me.
Not 100% of them are all exact same. And that’s specifically sprint cup. But regardless they are V8s making 900whp+ that are clearenced and designed around whatever weight oil they are using and they are heavily abused and seeing much higher temps for much longer times compared to what people would be doing with a daily driven Q.Interesting, although that's from 2013. March of this year showed 10w30.
Nascar engines are built to endure extreme conditions, for example, a NASCAR V-8 engine works well very high-temperature and pressure, the temperature insidemyengineneeds.com
