need some oil tips for a high mileage 97 F150
 

My 97 F150 4.6l 4x4 has 138000 miles on it. Whats the general consenus out there for a good high mileage engione oil?? Currently running 5W30 Penzoil.

stick with it... no need to change now... just make sure your using a FL-820 from Motorcraft

I agree on this matter.

Pennzoil sucks, when i got my king ranch the ford mechanic at the dealership said whatever oil you go with DO NOT put in pennzoil, then he pointed to three f150's that had the motor tore apart and they all had pennzoil in them, go with motorcraft or valvoline or castrol for a good oil

..............so your saying i fluked out by getting to over 130, 000 miles using Penzoil??

I personally wouldn't use Pennzoil. Seen some bad things happen from it.

Pennzoil is one of the top rated motor oils out there. I'd question any mechanic that thinks he can identify an oil by looking at it or tearing an engine apart. Sludge, FWIW, is not caused by an oil but water in the system that has overwhelmed the PCV system. Short trips, not running the engine at temp long enough, are the common factors in sludging an engine. Pennzoil gets my vote along with a quality filter like the Motorcraft or Purolator.

see if ya make it another 130000 miles :coffee:

Stick with what your running but do put a motorcraft oil filter on it. :thumbsup:

................We'll see. Don't forget my weather conditions are alot tougher than what any Texas Ford has seen. I had -46 celius the other day. Any vehicle that sees those conditions regularly and lasts past 100,000 miles is good in my books. Thats -50.8 Farenheit by the way.:D

If you had a new engine, I would say Motorcraft, but if you have 130,000 on it and it is performing satisfactorly, why change? I like sticking with something if it's working.

.....ahhhh a fellow Albertan. Now i feel at home.:D

ture but i bet your ford has never seen 110-115 degree days either, ive run motorcraft in it for 106,000 miles and at the end of the 5000 miles its still light brown and right at the full mark. Ill stick with my motorcraft :wave:

yuppers. guess we are at both ends of the spectrum.

we see 100 degree days in the summer and -50 in the winter. My buddies old escort would burn up penzoil like a siz and would use the cheep walmart brand stuff and the consumption was minimal. i wouldn't run penzoil in anything I got except for the penzoil platinum.
