Oil pressure gauge maybe too high?

[jcramer0005]

I got a 94 ranger with the 4.0. I just got my oil changed and added an STP oil additive to keep the engine healthy since it just hit 94k miles and the owner before me did not change the oil for 8k miles.

I noticed that my oil pressure gauge stays right in the center but than pins itself on the "L" where the normal word is when I drive about 35 miles but no higher. I felt the engine was running a little stronger than normal and figured it was the cold weather but should I be worried?. I did not hear any kind of knocking or tapping other than when I hit 75 mph on the highway.

Thanks

I have a 93 with a 4.0 with 280,000km on it I have owned since 200,000km. The gauge has always read to the high end, never in the centre. I would recommend an oil flush the next change and maybe consider a true synthetic oil to protect the engine. I am presently using Motul 5W40 and it has resolved a slight oil consumption issue. For yours the 5-W30 with such low km.. Really good product, expensive, but no need for additives.

wow 280k miles is crazy!

I never owned a ranger before so I just wanted to be sure. What type of oil do you use? I run mobile 1 in my cobra but it cost me $70.00 every oil change.

Motorcraft 5W-30 in every RBV I've ever owned and every one of them out lasted me... No reason to spend bookoo money on full-syn or fancy stuff... It's not going to make a big difference... Not using synthetic oil won't hurt an engine and using synthetic isn't going to help it anymore...
