oil

[seeker]

talking to a couple mechanics they said i should change my oil weight to 10w30 since its over 125000

that is really old school thought that you need thicker oil as the engine gets more mileage on it. People did that to lessen the smoke from the exhaust. Problem is that thicker oil flows slower. not what i want. Slow moving oil in an older/high mileage engine is a recipe for more trouble. Stay with the same weight oil.

Take a look at the diagrams on the oil flow in these engines. You wouldn't believe some of the near pin holes that the oil flows through.

I have been using Mobil 1 full synthetic 5-30w since I bought my Expy used last year, it had 48,000 miles on it and according the the oil change records the prior owner was using Penzoil full synthetic. I now have 56,000 on it and Unfortunatley I've noticed oil consumption at about 2 quarts per 4,000 miles so over the weekend I bought the recommended 5-20w Motorcraft blend and new filter as I'm going to see if changing to the 5-20w reduces the oil consumption.

u've stuck with the oil for 125000 miles, what makes u think u need another oil ??

i keep losing oil. i got the truck with 120000. but i was just curious to see what people think.

i lose a lot! maybe a quart or two. but i change it regularly so it doesnt worry me.

Go with a high mileage oil like castrol or penzoil, it has properties in them that actually help slow down the amount of oil you lose or burn.

i do. but 157+ miles dont help much. time for an oil change im over my 3000 limit by i think 68 miles. haha ill change it next week i think. when i do my fuel filter.

It's wierd, I have almost 196,000 on my X, and I don't use any oil, still running 5w30 as well.

really? weird. i think mines has always burnt oil. it was a drug runner for part of its life. so we dont know how it was driven. but its been in this family for most of its life. but who knows. i think it always spitts it out. my oil pan isnt the cleanest thing in the world. it needs a good hot steam power wash.
