Is this oil everything Castrol states it is. or is it like a snake oil with Castrol badging?
I apologize if this has been horse on the forum board, but I was seriously thinking about buying some and trying it. I know I won't be able to tell if it REALLY IS doing anything to my internal engine parts, but I guess I would have to trust Castrol at what they state about it. shrug

Well you can see if it makes your truck sound quieter. If it does then you can somewhat believe what they state. Many on here have reported excellent results backed by UOAs. Nice to see you back friend.

I've only used the semi-syn and the truck runs and drives soooooo smooth now. Best oil ever made.

Than You so much Sir! I am feeling A LOT better and am getting around a bit more. But I have only approached that hills peak. But, God is my answer to all of my problems.
Okay, next OCI, I think I will try it.

I ran it last winter and my truck was much quieter on start up then the previous winters running other oils. There are also some stellar UOA reports running Castrol GTX Magnatec

Seems to give great UOA and many say it quiets their engines.
Also cheap at Walmart (like $18 for a 5 qt jug).

I have some that I got from the Advance Auto clearance that I will be trying soon in the Scion. It does not make any noise, so no sure what to expect (if anything).

I can also vouch for quieter cold weather starts and quieter at high RPMs in my Subaru Crosstrek.

I wouldn't call it snake oil as much as just marketing. I am sure its a great oil.

That's right - a good product and they want more market share. Another day at the office ...

I scooped up a bunch of 5W20 from the AZ & AAP clearance sales, and as long as it's paired with a good quality filter (an XG2 on the 4.6)-it does seem to make startups quieter. I'm not familiar with the 4.2-does it have long timing chains like the Ford modular V8s?

I just bought 30qts from Amazon and I'm looking forward to giving it a try. It's crazy cheap right now if you buy in th 5qt bottles. From what I've seen here it's great oil, especially in the direction injection, turbo motors.

I use all grades of it but I buy it because it is rock solid to 10k on my vehicles.
Other than that I don't really care about the advertising.

If I wanted to use the slickest and smoothest oil that would be Total Quartz 9000 Future.
Amazing smoothness in everything I tried it in. But these days I mostly only use CM...

The Escape with the Eco Boost will see 5W20 Magnatec soon.

A good oil but with silly advertising.

By "intelligent molecules" read it as "polar molecules", this produces a net dipole at the oil molecule and makes it more attractive to metal surfaces, so it tends to stay on the metal and not drain away when the engine is off. Talking at the suface microscopic level here, not at the bulk oil level.

The 10W30 semi-synthetic ran very smooth in my car.

The 4.2 has a typical double roller timing chain.
Well, from all of these positive replies, it looks like my 4.2 V6 will be using Castrol Magnetec 5W30 or 10W30 next OCI, with a FU oil filter.
