I have a 1989 Ranger with 180,000 miles on it. I was wondering what oil is the best to use. Last oil change I used 10/40 and some STP additive.
Is this OK or is there something better? Do the lifters need Zink, or what?

Good grief, your using STP with 10W-40, that would make a concoctcion that would be something like 20w-50 or so, about like gear oil!!!! Don't know where you live, or under what conditions you operate under, but that OHC engine wasn't designed to run on lube anywhere near that viscous!!!!
I see you've asked this queston about your 189K mile 1989 2.3L on the 4cyl forum & haven't recieved any answers.
Not sure what Ford specified for that engine back in 89, but it was probably 10W-30 & later 5w-30 & is now 5W-20.
If your not in hot country, that engine sure is suffering during cold weather, having to try to pump such a viscous brew & the OHC needs cam lube Fast, on cold starts!!!!
So, I'd loose the STP in the mix & look to a good quality 10w-30, or 5w-30, or maybe even try Motorcraft 5w-20 thats been back specified for most engines since about 01, if it isn't leaking, or burning oil.
Some engine lube thoughts for pondering.

You should be using 5W30 or 10w30 unless the rings are extremely worn. Even thought he truck is an '89, it will love you for using a lighter oil. 10-40 is thick enough that it will cause excessive startup wear the only time you should use the 10w40 is i you are in a very hot climate like Phoenix. If you use the right oil, no additives are needed or recommended. Most engine wear occurs at startup. The faster your oil flows and pressure builds, the less wear, and the longer the engine can last. Heavy oil flows slower and takes more effort to pressurize. Some claim the thicker oil doesn't drain off the parts as much, but you will not notice a difference between a 5w oil and a 10w oil in terms oil residue left when the engine is off.
i run mobile clean 5000 10-30 truck seems to love it untill 4500 miles then i can feel a big hp loss, now i just change it every 4000 miles, with a K&N oil filter. i drive my truck on the beach alot and i like to take it threw the woods i think it would be fair to say that the truck gets put the the more then it should but its a ford and it will run for ever.

It burns about 2 qts. every oil change 3000 miles. I'll try just 10/40 no STP.
THANKS Paul
Is it leaking the oil, or burning it????
If it's leaking any, maybe consider a "High Mileage" recipe oil, that says it has "seal conditioners" in it's formulation.
Several folks on the Ranger forum have posted positive results with Valvolene's high mileage product.
If it's really burning that much oil per OCI, but engine wear isn't exessive, the ring lands might be coaked up & the rings are sticking such that they can't make as good a seal as they're capable of.
So maybe consider an Auto-Rx treatment, to decarbon the engine & free up the rings!!!!!
I've not had to use it, but some of those that have, report a reduction in oil consumption, apparently from the ring lands & rings being freed up to make a better seal.
If it works for you to lower oil consumption, then maybe consider opting for the specified vicosity lube for your engine, it sure would appreciate it on a cold winter start up!!!!
I would use a Heavy Duty Engine Oil (HDEO) rather than a Starburst Oil. These have plenty of ZDDP for anti-wear as well as strong deposit control additives to keep your engine clean. HDEOs are also designed to combat ring-sticking. For 10W-30 dino oils, you can go with Shell Rotella T, Brad Penn HDEO, PetroCanada Duron-E, and Exxon XD-3.
