Question Royal Purple To Eneos

Ever since i bought my car i have been replacing the engine oil with Royal Purple.
I heard a couple people mentioning Eneos. My question is what would be the benefits of using ,0w 50 rather than, 10w 30? Better protection? smoother? etc. i ask this because i am at 20,900 miles and my oil change is coming up..

Is eneos even offered in the US yet? I want to look into that oil too.
I've also been running royal purple every oil change.

Even though there has been talk about better protection from this oil, I'm still a little hesitant due to the 0w-50 rating....I don't even understand how an oil can have a viscosity rating of 0

I'm confused about that myself.

What I've heard about oil is that the first set of number indicate startup, and the last set is the protection rate.

Example: 10W-30

10w is the weight of the oil during engine start up.

30 is viscosity rating of the oil.

So 0w-50 will start up like a 0 weighted oil and protects like a 50 weight oil?

I need to figure all this out myself b/c i have the 3yr/45,000 mile free regular scheduled maint. package with my car so they cover oil changes but when they are done covering them i have to, obviously, buy my own.

And that's why we have the mfg reps here to answer any questions that you guys/gals might have.

Bottom line is this (from a non-techincal pt of view): the oil is designed to flow the same whether it's hot or cold. It starts good at low temps, but at high temps (where other brand of oil might start to thin out), the additives inside starts to expand and compensates for the thinning of the oil = thus providing the same flow rate and protection level... donno if that makes any sense.

Results thus far with the 0W50: Higher oil pressure, lower oil temp, increase in HP and Tqe, and a smoother running engine... that's not bad for paying an extra $20 for the next oil change... might be the best mod for the $ to HP-gain ratio.

...interesting...would this affect the tune since its freer flowing? What exactly are the HP/TQ gains?

Just to inform, the W mean "Winter" not weight which is a common misconception.

it won't affect your tune, but you will gains across the whole power/tqe curve
