Is this oil a gimmick??? Also some other questions about THINNER OILS...


GTX MAGNATEC delivers:

Intelligent molecules that cling to critical parts to provide an added layer of protection


I mean what addative package in oil does that?? And if its true that 75% of wear is on cold starts ** and Im sure there is some truth to that ** anyways... If this oil can do this... Why does Castrol Have EDGE Ranked higher as a better oil.

What do you guy think of this oil??

Reason Im asking is at work this oil went on clearence about 5 months ago and I bought 10 cases and a few jugs....I just changed the oil and ATF in my Acura last night.. It calls for 0w20... I was using for the 1st oil change MOTUL 0W30 but in the owners manual it clearly says 0W20... I have had many mechanics tell me that 0W20 is a EPA standard for better gas / fuel econemy.. however its at the cost of wear on your engine... So Im not a big fan of 0W20 and for work we had to go to a oil seminar and the key note speaker was saying how oils are going to even get thiner.. 0W8 will be on shelves soon.. I guess ROYAL PURPLE aleady has it also MOTUL has 0W8 already.,....

Correction; 0w8 is already on sale, on the shelves of stores aorund the world. We arent waiting for anything, its already here.

Castrol Magnatec is disingenuous and misleading - all oils sticks to metal and no molecule can be classed as intelligent. It's just marketing rubbish.

In the world of oil marketing that's full of gimmicks,Magnatec isn't one according to numerous real life UOA's published from times to times .
It's about oil polarity , among others IMHO .

I am told 0W8 tastes like olive oil.

Polarity is never a bad thing, and Redline is among the most polar oils. Consider that even when you use a non-polar oil, the inside of your engine is still coated in oil 6 weeks after you turn the engine off so we have to suspect that polarity isn't as important as people think, simply because oil clongs to metal even when its not polar.

Marketing claims are BS wrapped up in a nice package - 'intelligent molecules' is just a BS way of saying 'oil sticks to metal'

Virtually all oils cling to metal. Pour olive oil in a skillet and watch it cling. That said, Magnatec is a solid performer and I have had no problems with it. Of course, I never had any problems with other oils, either. Just keep the oil changed with any brand oil that meets spec and you will be more intelligent than the Castrol molecules.

Regarding Magnatec, it's by no means a bad oil, quite the opposite.
But all that stuff about intelligent molecules that cling to engine components is marketing BS, to grab the attention of people who don't know much about oils.

Marketing aside , I thought Magnatec has some ester and clings better. Not sure about any other proprietary stuff but it also may ... iirc, Shannow had some lunch or meeting with one of their formulator and if you search the site, you may find the info or the claim.

I have heavy oak doors in my house, and steel hinges. I only use redline to lube my doorhinges because the extra zinc means I can stretch my hinge change interval to 5 years. 0w8 isn't even thick enough to lube a skillet before frying a steak wink

Why do I picture "swinging doors" like an old country song-where's Merle Haggard (RIP) when you need him? I use Magnatec on the 4.6, I'm not ready to replace my sloppy chain set yet, has worked pretty well for 7500 mile OCIs so far.

Incorrect.

Group 4 and most Group 3 have poor polarity and work poorly as a solvent.

You PAO and Di-esters have good polarity.

Many AP have polarity. They were engineered as such and thus are targeted through the "intelligence" of the Chem - E.

I pull my DS in the VW with Motul 8100 and the oil is trying to flee the waterline.

I'm sure you noticed this with some oils.

Treat a cast iron pan with animal fats ( the original and best oils - what did you grease you chariot axle with?) and it will stay bonded deep within the valley of the asperities and above - even when rinsed with boiling water.

There are oil tackifiers, like is used in bar and chain oil, which must increase the surface tension. They can put a microscopic extra amount in, then the marketers can write their ads and the graphics dept. can make pictures of atoms and stars spinning to get our attention and buy it. The goal here is buy our oil instead of the other guys oil.
