Just to add to the never-ending debate on thick vs thin, here's a current BITOG thread about a fellow using 0w20 in his Caterham 7 race car where 5w50 is spec'd: http://www.bobistheoilguy.com/forums/ubbthreads.php/topics/4022868/1 There are many versions of the Caterham 7 with different...

Actually, I know more about oil than the dude on svt forum. Everybody knows that. I'm not being humble or anything, just stating a fact. I mean it is what it is and i know more than the svt loser. I have a Doctor of Motors degree from my high school industrial arts class. I crush the svt guy...

I think the svt thread being referred to is this one http://www.*******************/forums/showthread.php?805918-Official-GT-5-0-Boss-302-UOA-thread. If you can't read it, it has recommendations for various vis oils based on intended use. The author (a forum guru I guess) recommends sticking...

The viscosity ratings of motor oil express the time (usually expressed as Saybolt seconds) it takes for a volume of oil to drain through a particular hole or orifice. The thicker the oil at a particular temperature, the longer it takes to pass through the orifice. A 0w20 oil is actually a 5w20...

I'm just starting the process myself. I've found that unless there's personal injury as part of the accident, most lawyers won't get into dv claims. There are outfits like this one that will guide you and assist in filing a dv claim against the at-fault driver's ins co. -...

Actually, I've got the strut brace and am glad the dipstick is thin and easy to bend and manipulate around the brace. And for some reason you've got to turn the dipstick to get it to go in fully. You just have to use two hands; one on the end to guide the dipstick into the tube and the other...

There was an excellent online video clip (more than an hour long) that recorded a presentation by a Phd chemist from Afton Chemicals to the Royal Society of Chemical Engineers. Afton Chemicals is one of Europe's largest makers of additive packs for motor oil. The presentation was called...

RoyalGuard: What viscosity oil does your owner's manual spec? Here in the States, it's 5w20 that meets Ford's specification of WSS-M2C-945-A. Is that the same as your owner's manual? Just curious. To answer your question: I personally always stick with the oem's recommendations. So, I...

MC oils are made from S-Oil Super S base stock; very high quality group III+ base stock refined in South Korea from high quality Saudi crude half a world away. S-Oil exports this base stock to countries all around the world. Conoco/Phillips makes the finished MC oils, and Conoco/Phillips is...

Curious. How do you know Mobil 1 0w40 is a PAO grp IV base stock?

Was that part of the car repainted - - maybe accident repair? It's hard for me to tell from the pics, but I've seen moisture spots (not water spots) like that due to moisture in the air line to the paint gun. It kind of blooms over time as it rises up to the clear coat. It can also happen if...

One of the reasons to let the oil warm up and get hot before demanding high rpms and max power is to get the oil to thin out some so it can circulate well and flow quickly and evenly to all the engine internals it needs to lubricate. This isn't that much of a problem with the Coyote's thinner...

I don't have your long association with Ford; my 2015 Mustang GT is my first Ford; prior to that, 20 BMWs over many, many years. But I'm really liking my new GT. A very experienced lubricants engineer named Doug Hillary (some of you who regularly surf the BITOG oil forum may know him), who has...

I think it's fairly well established under the Magnusson-Moss Warranty Act that a mfr cannot condition its warranty on the customer using only certain brands of products, but it can condition the warranty on the customer using products that meet a prescribed performance standard available in the...

That's an outstanding uoa. With these kinds of results, i can't understand why some folks are so afraid of 5w20. It would appear Ford knows what they're doing.

There are many service fill oils, intended for oem's extended drain intervals, that have moly in them. Some do, some don't. http://www.pqiamerica.com/Feb2014/consolidated5w20ALL.html. Strictly speaking, moly is a friction modifier, designed to increase the lubricity of the oil, but most...

And they could have any number of organic esters for wear protection which won't show up on a uoa. Extra wear protection and moly = all the more reason to keep that factory fill in there.

Thanks for the info and link.

Thanks for posting. Wish more folks would post theirs when they have it done. Looks like a very good report. No sweat running the oil longer.
