How is the mobil1 "Advanced Fuel economy" full synthetic 0w-20? Every once in a while costco has the 6 quarts from 38 to 28. Or should I be using a different mobil1.

If you can get it for a good price then that is what I would use. It's a good oil.

It's what I have been using primarily. It's a pretty commonly used oil over at Bob is the oil guy forums.

I can't keep Mobil1 in any of my vehicles, I think it evaporates. There's never any drips on the driveway, or smoke out the tailpipe, but it goes somewhere. (Probably out the PCV.)

I'm a big fan of Mobil 1, I used it in my S10 and put 310,000 miles on without ever using any between changes!

Oh wait...... it's only purple after it comes out........ It goes in as Amsoil 5W20 lol. My truck is special....... I make Royal Purple by using Amsoil!

This is a comparison a couple of friends and I did a few years back. Both of these guys swore by each brand of oil and never swayed to any other brand of oil. I also have always used RP in every vehicle I have ever owned. I also use the transmission fluid/filter.

 

All of the trucks I have owned including a Porsche Carrera and Viper I currently own use nothing but RP. The cars and trucks all average about 15 degrees cooler operating temps and the trucks I have owned/own have picked up an average of 1.5MPG increase.

 

These pics speak for themselves.

Mobil 1 for sure.

Why change.

Gave me 286,000 flawless miles in my '98 Silverado. :thumbs:

 

I'll bet that camshaft was in pretty darn good condition too. :)

Pictures will tell for sure.

Of those two cams pictured... one could have just as easily had inferior surface hardening over the other... the oil used likely didn't mean a thing to the wear pattern developed on the Mobil 1 run engine. By the damage on that cam I would bet money it's a surface hardness problem.... I have seen a lot cams in my life and in 40000 miles running bargain basement bobs dino oil the surfaces should not look that poor.

These pictures are the real deal. Both owners are good friends of mine and each of these cars were being torn down to be built to pro stock. We thought we'd try to put to rest the continuous arguments over which oil is best or not.

 

Your comment just shows that no matter what type of physical, scientific or WHATEVER evidence can be presented that some people will never be swayed.

 

To each his own ....... use whatever you like. I do. :D

No evidence or science behind it. You pulled cams out of 2 engines from different model year Mustangs, tossed them on a table and said yep, the oil screwed that one over. That's about as unscientific and inconclusive as you can possibly get. It looks bad for Mobil, however, if you dont verify correct oiling on that cylinder head or the hardness of the cams finish... you didnt prove anything. I don't even run Mobil 1... I have no loyalty to oil... just like vehicles.

      286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔

      cam upgrade in CA

      By AidenVorpagel · Posted

      hello I recently bought a 2012 gmc 1500 with a 5.3 and have a AFM disabler on it I'm interested in doing a cam but I'm worried if I remove the AFM system I will fail smog does anyone have info if they are able to detect that or a work around to it (not talking about hot smogging) please let me know thank you

      Possible lifter tick after DOD delete

      By B14Sierra · Posted

      Update. I started chasing down my symptoms. Started first with pulling valve covers and looked at everything. Everything looked good and couldn't hear or feel anything different. Then a compression test. 240 psi or really close on each cylinder. I was worried I was a tooth off of timing. Not bad for an engine with 173,000. Granted I did put new heads on. I sprayed water around the injector area to see if I could hear a change. Nothing. I hooked up my new hp tuner which I should have done in the first place but I don't really know what I'm looking at just yet but am learning. I noticed the fuel trims were way off so that told me I have to have either a bad injector or exhaust leak. New injectors, so I did the shop vac on blower and in the tail pipe. Sprayed soapy water and found the exhaust flange on the drivers side was leaking. I didn't think it would be that considereding I pulled the heads and left the manifolds attached. I did have the transmission replaced not long ago. They must have not seated them properly but I guess I didn't notice. I put in new gaskets on both sides. Which by the way isn't a bad job but I had a hard time getting them to seal right. Took two attempts. Reset the fuel trims and the ticking is gone, engine runs smooth and acceleration has improved. Got to feel the real difference with that stage 1 cam. It's not that big of a difference but it does add a little more. It feels like how the truck should have been from the factory.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.
