What is the oil temperature range in a stock 1.4l Cruze?

I am looking to purchase an oil temperature gauge and need to determine the range needed. I understand the median temperature should be at the 70% mark on the gauge, but I do not know that (those) temp(s).

Thanks

I didn't think the 1.4 turbo had an oil temp sensor? Where are you going to put the probe? Curious as when I hook up a scanner, I have no readout for an oil temp, but my Torque app does but I believe it is a calculated temp, not exact. The torque app runs up about 230 degrees give or take when warmed up.

Well, I am not sure yet. I first had to decide whether I wanted to monitor oil pressure or temperature. I read quite a few posts and plenty of outside information and while the answer seems to be a toss-up, based on what I read, temp is the way to go if you are not heavily modified/tuned. I may do a tune in the future, but I also like the reliability that being stock provides. I guess I need to read on where most oil temp gauges are connected to now.

EDIT:
And just for grins, where would I connect an oil pressure gauge?

Cartridge filters are found on the genII 1.4t.........most likely a Autometer fitment error since genI is a canister type.Rob

I have always seen the terminology used exactly opposite..."canister" = metal filter like Gen II; "cartridge" = insert filter like Gen 1.

Drilling an taping the oil pan would likely give the best general Oil temp, This AEM one looks to be a pretty good kit: https://www.amazon.ca/AEM-30-4402-100-300F-Transmission-Temperature/dp/B001DX9KJK

The Cruze does have an oil cooler does it not? Personally, I would be more worried about burning a valve than overheating the oil, I would recommend a AFR Gauge or EGT over oil monitoring, Just make sure your running a good quality synthetic ;)

@dtuerk, why do you recommend air/fuel ratio or exhaust gas temperature? Also I plan on going with Autometer and using the air gap type so it is as close to analog/mechanical as possible without routing an oil line to the cabin.

dtuerk has a point, the only place the oil temp matters is in the turbo bearings, so sump temp will just tell you if it's getting hot enough to get rid of all the moisture.
I'd rather have trans oil temp than engine oil temp, and I'd rather have EGT than trans temp.

Torque app will read oil pressure and temp. But you have to fill in the correct PID information as torque app doesn't have the correct information. I have the PID information but i don't think the pressure is reading accurately. Oil temp seems to be somewhat accurate though.

OIL temp WILL NOT read higher then coolant temp. It's impossible for the oil to read higher temps then what engine is running at. Except maybe for a few minutes after the engine has been shut down in the middle of summer. I've been using torque for a month now and have yet to see oil temp go higher then coolant. @ 190 degrees. But it's FALL season.

There's one post on here somewhere claiming he got rid of his car because his oil temp was reading 240 - 260 degrees. I"m pretty sure the engine would have fried long before the oil got that hot if that were the case. That would mean his coolant temp was also reading that hot or hotter.

A Cruze with an external oil cooler might never see higher oil temp than coolant temp, but not only is it not universally true for other cars, a car without an oil cooler doing heavy work like towing will almost always have higher oil temp than coolant temp.

The coolant temp is controlled by thermostat at freeway speeds with adequate air flow. The oil temp just is what it is.
Oil in the head tends to be close to the temp of the coolant in the head. Oil in the bearings can be cooler or warmer. If you have piston cooling jets, the piston cooling oil gets a lot hotter than the coolant. If you have a turbo, the turbo bearings are likely to be the hottest parts in contact with any engine liquids.

^^^Yup.

240-260* sounds exactly right for oil temps considering the engine itself runs around 225-230 water temp.

Cruze's fuel map goes pig-rich in moderate to heavy boost or wide throttle openings to keep EGTs down. They will typically run hotter on 87 oct, as the car retards timing a bit, but I don't think anyone's burned a valve on the 1.4T yet. There may be issues further on in the cars lives if the valve stem seals start to leak, but I wouldn't really worry about it right now.

I'm running a veepeak obd2 plugin with the torque pro app showing oil temp

Oil temp in the Cruze is an extrapolation, it's not measured. There's no oil temp sensor. There's no DTCs that set for oil temp either. If you're gonna pick up a gauge, I'd get one that goes higher, as opposed to one that starts lower. I'd rather have a 140-300 than a 100-250

EGT is a valuable bit of info, but only if you know how to to interpret it in relation to other data (namely AFR), if you don't, then it's virtually worthless as you can have a certain EGT and being running on the rich side to attain it or attain the same EGT and be running lean. If you dont know both, and can't montior them simultaneously, and can't time for that situation them it was all just a wasted exercise for some cool gauges. I love cool gauges....buy whatever you like, but don't put too much faith in anything except coolant temp, and oil pressure. LOL


Holy ghost thread.....dang.
