I have a new car that runs the oil a little too hot for my liking. It's new and it's considered normal but to me it's a wee bit too hot. This car has a digital oil temp gauge and it routinely runs 225-230F driving easy and will quickly go up to the 240's if you play with the go pedal. So far it's been as high as 249F driving up a mountain road and I wasn't even hot-dogging it since it was under the full-use break-in mileage recommendation.
The manufacturer 'recommends', yet requires an oil change every 6 months under warranty or 6 K miles whichever comes first. ( If you want the engine warranty to remain in effect.) I'm at 1,203 miles and I will be changing it with the manufactures recommended Pennzoil Ultra Premium 0W40 and a high perf "SRT" OE filter.
The car already comes with a factory oil/water intercooler and it still runs this hot. (The coolant temps stays between 215 and 227 most of the time.) Again, supposedly normal. So, when I change the filter I'm going to add this doodad to the outside of the oil filter since I've had it laying around the garage for about the last 30 years and now I finally have use of an oil filter that it will fit on. It may not do anything but I'm guessing it can't hurt.
