As the title suggests, I am looking for OCI recommendations for this application, an '09 Caliber SRT-4 w/ the 2.4L 285hp turbo engine.
Vehicle currently has 83k. 90% of my mileage will be highway with 35 mile commute each way. Won't be working the engine hard except for some brief spirited driving every now and again.
One of my goals is to get the best fuel economy I can, so ideally I'd like to stick with a 30 weight oil that meets specs.
Vehicle manual says to use Synthetic Mobil1 0w-40; my suspicion is that their emphasis is on a minimum HTHS value, thus recommending an oil that meets ACEA A3.
I've seen some Mobil1 High Mileage oils in 10w-30 that meet ACEA A3, as well as GC 0w-30.. For some reason I've always tried to avoid the HM oils. Are there any other A3 rated oils out there? What would you guys suggest? Would there be any harm in running a typical 5w-30 / 10w-30 type oil like 99% of other cars recommend? Do you think synthetic is a requirement or could I use a 15w-40 HDEO in summer..?
As you can see, I'm throwing out a lot of options so I'm open to any suggestions as to oil type, weight, interval, etc. Any input would be appreciated.
