I am currently a high school student. I don't drive very much. Just to give you an example, i've put 2,500 miles from June til today. My school is less than 1 mile away. Every morning, I pick my friend up (1 mile away), drive my sister to school (2 miles total), then to the career school (4-5 miles), getting on the highway in the process. At mid day, i drive back to my home campus and let the Jeep bake in the 100 degree sun. After school, i drive home. 20 min later, i'm back up at school for band. 2 or 3 hours later, i leave. Thats my daily routine. I do drive around town sometimes. I am currently running an O'Reily Auto Parts oil filter (Purolator Premium Plus) and Mobil Drive Clean Plus. I am considering going over to Mobil 1 on my 95 Grand Cherokee. It doesn't leak, it has 69K miles. I know I can make the swtich without problems.
When i start up in the morning, my oil pressure is about 60 psi at idle. Thats the max PSI it should be on a 4.0L i-6. When i start moving, it gets to 65-67 but 65 is the max when moving. Should i let the Jeep warm up a little b4 i drive it? I dunno if thats the pressure going into the filter or coming out. If its the pressure going in, then its ok because the pressure drop on a Purolator Premium Plus is enough to put it back into the safe range.
So, should I just run a high quality dino oil or blend like I am now, or swtich over to Mobil 1 for the extra protection. It gets hot down here. It will be hot til the end of Sept - mid october. Sorry for the long length! Thanks in advance!!!
