The reason you heard lifter noises after changing your oil is because that 0w is SOOOOO light weight that if you had any slight motor or lifter noise before a lighter weight oil doesn't weigh the "ticking" lifter down enough so it ticks louder. You put a heavier weight in there and since it is thicker it coats the lifters more reducing the noise from the valvetrain. If you wanted to continue to run the 0w-30 GC I'd try adding a Lucas oil additive such as the regular ol' Lucas Oil Stabilizer (I've used and stood behind this stuff for noisy, oil burning engines for over 6 years) but I use their new stuff called pure synthetic oil stabilizer it works really well with all pure high performance synthetics that are going to be run hard. If you were to use the 0w-30 and add a quart of the pure synthetic in there also I don't think you'd ever hear a lifter noise again and your motor would benefit then from the lighter weight oil by being able to rap up a little quicker from not having to use a heavier oil just to cover the noise up. Give these items a thought they work. BTW the lucas additives can be used in noisy diffs, trannys, and even if they aren't noisy it really helps by making the rolling resistance less.
LMFAO

I'd have to agree. Thats such bullshit its not even funny..

Hmmm, a 0-30 weight oil is simply lighter when cold then a heaver oil. Even a 20-50 weight oil is lighter in viscosity when hot than a 0-30 cold.
Lucas additives have shown in tests to make oils foam a lot, which is very bad.
Decent oils have their additives properly engineered and balanced. Adding additional additives will change that balance and the oil won’t be able to function as designed.
Use a quality oil straight, without additives.
Virtually all the oils discussed here are great, top tier lubricants. I’d use any of them. I use Castrol German because testing has shown they have a good advantage over other oils throughout the life of the oil. If I couldn’t buy it, I’d reach for a Lucas full synthetic or Amsoil.
Remember guys, the filter is equally important as the oil you use.

"lighter weight oil doesn't allow your motor to rev more freely"
I’m not getting what this means. A lighter weight oil will allow you to spin more freely. HOWEVER, at operating temperatures, most oils have pretty much the same viscosity, regardless of the cold rating.
The cold oil rating helps allow the engine to have less wear until the engine/oil reaches operating temperature. Once everything is hot, the oil flows quicker than water.

: Sorry if I offended you and came across as an ***. I am just pissed about some other stuff right now
Thicker oil can SOMETIMES make a noisy valvetrain a little quieter but it has NOTHING to do with "weigh the ticking lifter down" or "coats the lifter more". It is because it can apply more pumping force to a worn out lifter. It is pretty obvious you don't know what a lifter does.
2nd, I whole heartedly agree with PB on the oil additive issue. NEVER run an additive in todays oil. Lots of R & D $$$ has gone into developing oils to run in modern engines and if you have to add something to it you are running the wrong oil to start with. And Lucas IS a bunch of foaming crap!!! You could have made a worse recommendation though and suggested V-Max who has a lawsuit against them right now
PB posted all good info. Read it and learn. Or better yet google bobistheoilguy. TONS of good info there.
This is funny why?
And again why so funny? I have had S-10's all my life. They have an inherent ticking lifter noise. I've always used a heavier weight oil to "quiet" them down. The heavier weight being more viscous keeps a heavier film on the lifter so when metal makes contact it isn't so much metal to metal there is a thicker substance between them (in this case a heavier weight oil) to quiet the lifter down. If you used a lighter less viscous oil you would hear it more because the metal contacting each other isn't as enveloped by the thinner oil. I have used the lucas oil stabilizer with good results also to "quiet" a noisy valvetrain down. Once again a more viscous liquid will help to quiet the metal to metal contact.

If you look a little higher in my posts I said a lighter weight will allow a motor to spin more freely. When sombitch lol'd at that I was saying then if a lighter weight doesntallow it to spin more freely then why does everyone use it. It was meant to be sarcastic as I agree using a lighter weight will allow it to spin more freely.

You still clearly don't understand the whole damn thing. A 0W-30 is NO DIFFERENT than the same oil in 10W-30 when up to opperating temps. the first rating is nothing but the cold viscosity and even then, a 0W is to thick to provide proper lubrication on startup to prevent shearing. The whole a lighter oil will help it rev up faster is true, obviously, but if you understand what I just said, it doesn't ******* matter. A 0 or 5W won't help AT ALL once its warm, which is the only time it matters. Unless you rev your engine when its cold.
