and with the tighter tolerances in todays motors...5-20 will get in there and lubricate things better

Again, I'll say that a 20wt oil is too thin for that motor. K.low, why don't you ask the dealer to document that 5w-20 is OK for that motor. If they can, then I'm happy to admit I'm wrong!

I have used 5-20 in my Ford for a long time.
Anything heavier causes the lifters to get noisy, at least for me.
Both my 5.0L and my wife’s 4.0L got noisy lifter, my latest 3.0 has never seen anything other than 5-20 Oil but now Synthetic Oil.

If the Dealer put it in and IF something goes wrong then the Dealer will have to cover it, don’t worry bout it !

Ford approved almost everything gas they made from 1993+ for 5w20. I dont see the big deal. I've used 5w20 several times now

Don't worry about it, I have accidentally grabbed the wrong weight oil before and it was fine.

Well gosh I'm at 65K and running great on 5W20. Here's a partial explanation on why Ford switched in 2001 to including 5W20 in a lot more vehicles.

By the way, I don't ask the dealer ****. They like to lie and aren't experts or anything. They're lowly paid grease monkeys. I honestly don't know why you think it's appropriate to warn someone that 5W20 could be bad for their vehicle when NO ONE has ever complained that thin oil destroyed their engine. You also have shown that you have no experience running 5W20 (which is sold in a huge section at the store and many current ranger owners in northern climates are running).


Quote:
The main reason 5W-20 was specified for your engine is to increase the CAFE (Corporate Average Fuel Economy) reported to the Federal Government. CAFE is the combined average fuel economy of all of a vehicle manufacturers product line. Minimum CAFE levels are specified by the Federal Government. In order for a vehicle manufacturer to continue selling profitable large trucks and SUV's, which typically have poor fuel mileage ratings, as compared to smaller cars, and still meet mandated CAFE requirements, they must also sell enough of the smaller cars which have much better fuel economy ratings to offset the poor fuel economy ratings of the larger vehicles. For model year 2001, the change to a 5W-20 oil will allow Ford and Honda's overall CAFE to increase by a very small amount, typically in the tenths of a mile per gallon range. 5W-20 oil is a lighter viscosity than a 5W-30 oil and therefore has less internal engine frictional losses, or less drag on the crankshaft, pistons and valvetrain, which in turn promotes increased fuel economy. This increased fuel economy is virtually undetectable to the average motorist without the use of specialized engine monitoring and testing equipment under strictly controlled test track driving when compared to a 5W-30, 10W-30 or a 0W-30 viscosity motor oil.
Once again, I'm only wondering why you're saying a product viscosity is bad when you have 0 experience with it and I have never seen an "My oil was 5W20, HELP!" thread.

I'm with PW01, if I had a 4.0, I'd get rid of the 5w20. The issue isn't with tolerances. The issue is with the oil pump.

How many times do I have to say "NORTHERN CLIMATES"? Two guys from Missourri and Kentucky shouldn't be telling someone from Canada what oil to use.. Have you ever started your truck on a winter day and had the engine roll over slowly because it was so cold?

in the summer i use a 5/30 blend

but totally agree with the 5/20! once it hits november here in oregon that's what i switch to

no issues with my truck whatsoever

granted i do have the 3.0 but my friend has a 96 4.0 and has used nothing but 5/20 in it and his truck just rolled over 200k

I've started a 1.8L with 20w-50 below zero. It really didn't like it...but it did it. Believe it or not, Missouri gets cold too...just not as cold or for as long.

In cold climates, based off of the viscosity rating, a 5w-20 and a 5w-30 should flow the same when cold. Once up to temperature, then that's when the 5w-20 should be thinner than the 5w-30. However, once up to temperature...the outside temperature shouldn't really make much of a difference since the engine is keep the oil temperature up. If you really wanted a thin oil for cold climates for your initial cold-cranking...you'd get something like a 0w-30. Am I missing something?
