Best Synthetic Motor Oil?!?!?!?

[JoeliusZ28]

Help me out, how is synthetic a thinner blend?

a thinner blend is the wrong term, however i do not know the right term. viscosity maybe?

Put it this way. If synthetics werent thinner, they wouldnt be able to advertise better gas mileage.

You guys gotta be kidding me!!! Who worries this much about Engine Oil???? adding HP and TQ with OIL!!!!! Naughty Koolaid .......

If you run synthetic oil you are spending way to much money for oil haha sucks for you..... that could be gas money or even some mod money.... lmao

haha sucks to be you!! You're just wasting your money on extra gas BECAUSE you used cheap oil, instead of buying decent lubricant and cutting your gas costs (more than you spent on lube). By saving this money, the rest of us can spend more $ on mods. Hahaha, really really sucks to be you. rotflmao
lemme guess - you also use low octane gas because it's "cheaper", right? Come on, admit it!!

As an aside, for those of you who haven't gotten around, in other states (like OK, which was a major oil pumping state) they sell gas at the pumps with the following octane ratings: 85, 86, 87, 88, 89, maybe even 90. No 93 or 92 octane. And they sell each of those other ratings at different prices. It boggles the mind.

I don't want to be the know-it-all new guy, but I do know a good amount of oil tech..

Synthetic will always be a better oil. I'll explain why in a minute The only instance this is not true is new engine break-in, which is an elaborate procedure. A conventional oil produces a better break in because it produces more friction. This is great for making perfect clearances, but bad for the long term use of your engine.

A conventional oil molecule is taking from the ground and then refined. Certain processes and additives are added to the oil, but it's still the same basic molecule. It can't get any better.

A synthetic oil molecule is produced with all of the qualities desired in an engine oil but none of the drawbacks. All the traits such as film strength, film sheer, coefficient of friction and absortion of contaminants are at their peak within a synthetic oil.

Now for the myth that synthetic is 'thinner'..
What's heavier, a pound of feathers or a pound of stone?
See what I mean?
The weight on the bottle isn't relative to the type of oil, it's a tested number. That's the oil's viscosity at regulated temperatures.

The reason that older engines leak when they are run on synthetic is because they have larger clearances from the conventional oil. Your motor is actually 'held together by the crap' when you are running a dino oil. The synthetic oil performs a cleansing of every surface and new leaks tend to develop. If the leaks are simply cleaned up and more synthetic oil is used, the seals will generally swell back to their intended size and the leaks will cease.

There's more to this but I believe this is far enough. I didn't gank any of this from a search engine, this is straight from the keyboard.

Case in point, synthetic is always good for your engine, no matter what the age.

EDIT - If you're looking for a quality oil, Castrol Syntec is actually proven to be the most protective to your engine. You must read the label though.. If it's Made in the US, it's bad. If it says Made in Germany, it's the best oil that money can buy. Quality control is different between the US oil and the German oil. It's difficult to find the German blend but it is worth it. There was an extensive scientific study on this performed by many labs, this isn't just a graph on some forum. Amsoil is also an exellent performer, it offers much more protection than required for the clearances in a production engine. They both have execellent additive packages that last far past the duration between your oil changes.
Mobil 1 is actually a poor performer. It has been known to have a different viscosity between bottles even if they are labled exactly the same. Quality control is very lacking. Oils such as Penzoil, Quakerstate and other name brands are not worth your time or money.

Insomnya3AM,
Wow! New guy had a lot to say.
You got me convinced.

Question: Are all synthetics better than dino? Or should I run out and drain my Mobil1?

I'd say leave in the Mobil 1. It's a great oil compared to dino, but I wouldn't run it again. I can't say ALL synthetics are better than dino, there are some poor synthetics out there and some reasonably good conventionals.

Christ guys its oil. You should change it when its dirty, there isnt a set number of miles, it varies with your driving conditions.

Oil is going to get contaminated no matter what type it is. Use what the manufacturer set for your engine.

And as for gaining mileage, HP and TQ, you guys are pipe dreamers. Any difference would be minute.

This is the difference between a 70k mile bearing and a 350k mile bearing.
It's not about gaining mileage, HP, and TQ. This is about better lubricity, improved cooling, and decreased parts wear.

Oil and tires are the two most important decisions you can make..

[1bad83ta]

now drew I think your stretching the truth a bit there. Maybe your trying to make a point but I had a saturn that had 300k miles on it with regular motor oil.

[Orange Terror]

Thank you Drew, you said it better than I could. I'm with you 100%. I've also heard good things about the German Castrol but I just can't bring myself to run it, they sponser John Force, he's an idiot IMO. Stupid reason I know but I just can't do it. And after seeing a motor pop on AMSoil I won't run that either. I may switch off of Mobil 1 though now. Not sure.

Hey Justin, what Drew is saying is that while your Saturn may run fine with 300k on conventional oil, the same car with synthetic for those 300k would show less wear inside and be cleaner.

Couldn't have said it better myself. Thanks homie.



I agree: John Force is a re-re, hahah.
