No. The exhaust manifold transfers a lot of heat to the dipstick, it's not uncommon to see the dipstick smoking a little when you check the oil after the engine has been running for a while, especially if you're driving at slow speeds.

Just out of curiosity why do you run 5W50... maybe 20W50, but I thought 5W50 was for new cars or something. (based on the fact that it is a pretty much brand new weight of oil)

5w50 is for cars i would go to 20w50 it will be better protection for your truck. I my self use 10w30 and a bottle of lucas additive witch jumps it up to about the same as 20w50. Yes the smoke is fine mine has always done it after i put my headers on.:goodfinge

thicker, hangs around on your moving goodies longer, a lil more sluggish but better protection, i like 10w40, best of both worlds i would say

Standard filter? Or dos it require a different one? And does it negatively impact oil pressure?

Run 10W30 during the hot times, 5W30 during the winter months. If you have a tick, you might switch over to a Heavy Duty Diesel Oil (HDDO) in 10W30 (Mystik JT-8 is a great one) which has much more cleaning and protective capacity then gas oils ever could hope for. If you have an old worn blowby'ing engine then a diesel-rated 15W40 would be a good bet.

Those heavy 20W50 oils...I hope you guys live damn close to Mexico. The "protection" you get with that heavy of an oil at operating temperature costs you A LOT of wear and tear every time you start your engine up. Which..guess where most wear occurs. At Startup.

Alright last stupid question.....what is the difference between 10/30 and 10/40? I used to have a Cherokee that I ran 10/40 in and I have a whole case of it left. Can I run this safely in the Bronc?

The second number is the viscosity @ normal operating temperature, i.e. it acts like a 40-weight motor oil at ~190 degrees. Stick with what the factory recommends, and don't deviate from that unless you live in an extreme climate.

I used 5W-50 in my Mustang's engine. It's now sitting on an engine stand due to rod bearing failure. 'Nuf said.

Factory says 5/30 but this is 190,000 miles later. Shouldn't i be looking to run something a little heavier....especially for summer?

I like 10w40, it's like quiefanator says you get the best of both worlds. My 86 302EFI had a rebuild before I bought it and the motor has maybe 35-40k miles to date and the oil holds up, I change oil/filter every 2500-3000 without fail. I Sea Foam inside and out periodically and it runs strong. Not a lot of power, Not great on gas, but ya just gotta love them Bronco's. They're like children who need a lot of attention. lol
