I would never use 0-20WT oil.

[HelmHoltz]

Not sure where to post this since the CB7 never was required to run the new car thin oils, but this is a good read.

I ran 15-50WT Mobil 1 in a 1989 Honda prelude for 280K miles without any issues back in the day!

Did you even read the link you posted? At no point does it give a reason not to use any weight of oil..

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.

eh.. i'll just keep using 5w20 because that's i have a surplus of.

[Night Wolf]

the newer hondas use 0/20. but at my dealer, we just put 5/20 on those. unless the owner asks for the lighter stuff. & I wouldnt rock 5/20 on an old ass car.

OP - Whats wrong with 0w20, and whats so great about 15W50?
I fail to understand the point of your Thread.

Acclude91 made a thread a long time ago about using 0 weight in an F22A, and how it quieted down valvetrain noise. He was presented with some opposition from an aged member that spent most of his life working in the oil industry... so while I believe Acclude91 generally knows what he's talking about on most topics, I was never sure if that was one of them.
I personally have no idea. I run factory spec oil. No reason to do anything else.

[wed3k]

as an engine machinist, i honestly don't really know or care for the weight of oils.

i just throw in whatever is cheapest and most available which is mostly 5w-30. unless race car, then i throw in synthetic.

[deevergote]

I do factory recommended weight for the Fit, but always synthetic... because I put 10,000 miles on it between changes.

[Losiracer2]

I run 0w30 in my H22, change it every 3k and its been fine. I used to run 5w30 and it burns the same amount as it does with 0w30 since H22's usually go through a quart every 1500 miles....if you drive it hard like I do.

Use whatever you want. I run 0-30WT German castrol ACEA A3 rated. I do not expect for you to understand my post. You would need to go over to the bobistheoilguy Forus and study first.

Thin oils do not protect your bearings under load, but I also do not eat at McDonalds so I am wasting my time here.

You might appreciate this link my friend.

Kids,
Oil to be used depends on several things. Clearances, time between changes,(oil filters factor in too), power produced by the engine will dictate the ht/hs needed to keep metal tometal contact from happening. A 20w synthetic will have near or better ht/hs than a 30w conventional.

Additive packages are where the differences really are. I always run 10w30 in my accord. 5w isn't as good. If you understand additives you'd know why.

Your the one that created the thread with very little original information,
Now you don't even want to explain your original point

he just wanted to chime in and make his presence known and that he knows more than the average bear.

he just reads a lot on bobistheoilguy

The motoroilbible, I remember this. I used to run the 76 pure synthetic 5-40WT in my cars. Now they dont make it anymore? I will check to see if they updated the data.

My point of this thread was that the Dealers are compelled to encourage you to stick with the oil that was used for the CAFE testing. Oil should be selected per your specific circumstances. In Japan they run 40wts in the same engines that are running 20wt here in the states. It is all politics!

evil dude, I was not trying to be rude. my post was taken wrong and veiwed as an argument for some strange reason. Here in the States the population has been beaten down by the Green movement to use 20wt oils and buy a prius.

I just stumbled on an old bookmark that helped my case whenever people always say that the powertrain engineers are the ones that recommend the 20wt.
