I've actually seen them parked in front of Walmart before. I thought they were there for show but I guess they were buying oil for the next race.They buy oil at walmart

I'm running 10w40 in my 2002 Ford Escort that's spec'd for 5w20. I don't know what the previous owner ran in it but I bought it at about 80K miles, it's now got over 210K and is doing fine. I ran 10w40 in my '88 Escort that spec'd 5w30 and retired it with engine compression 145-155 PSI across the board at 518K miles.

Wait until the author realizes there are four seasons and what happens to oil during winter.

YA, IT GETS THINNER, RIGHT? /s
5w-20 is fine if you drive like a grandma.
Just so. Here in the US, Dexos 1 is gas and Dexos 2 is diesel, but Dexos 2 is gas in Europe as well as diesel.

I did not mention inadequate lubrication at bearings, I was discussing the critical bore lubrication through oil sling off the rod big ends, Though if you extend this to a logical extreme you WILL starve bearings with a certain high viscosity due to inadequate flow presentation. This would be likely COLD oil and Cold coolant / engine temps and extremely high viscosity in the sump.
I have not seen it discussed that many races engine use high viscosity oil but it is dry sump and often PRE-HEATED
Also 50 grade after adequate warmup is not excessively viscous for even under 0.0010 radial bearing clearances, though care is taken in how the oil is presented to the bearing through elliptical journal orifaces and other shell modifications. There has been much trial and error in the past before flow could be modeled with more widely available "affordable" supercomputers and associated software.

Of If you have an engine put together better than a Hyundai
I LOVED my 1995 Accent. The best Hyundai I owned over this, an Elantra and a Sonata - all manual and all wailed on.
Hyundai was using Porsche in the development and this made for a very capable and fun to drive buzz bomb

1994-1995 was when Hyundai was seeking a reversal of their fortunes - and over 20 years later they did well. I think that Elantra was the first to be in-house developed at Hyundai with little/no help from Mitsu. Before then, all of their efforts are rebranded or somewhat changed from Mitsubishi engineering and design.Of If you have an engine put together better than a Hyundai

The wife's 2012 Elantra 1.8 has done fine so far on 5w-20 for 115k miles. She drives it like an F1 car, don't think it sees much under 3k rpms except at stop lights. Other than brakes, a VVT solenoid, and a belt, haven't had had issues. Trying out QSFS 5w-30 this oci though, just for giggles. It's about the same at startup, maybe a bit noisier actually, even she has commented on that. But it is a tad quieter when hot. Otherwise not much difference. Going to try M1EP 0w-20 next oci and see how that goes, will be just in time for winter I think.
As in all the past discussions about oil viscosity, as long as an appropriate "W" rating is used for the ambient use conditions, lubrication of all parts should be adequate ... even for bore lubrication by way of rod big end oil sling-off. As a dumb kid, I had 20W-50 in my Ford 289 and fired that thing up in the winter when it was so cold the engine could hardly turn over. I never saw any ill effects, even though a 20W was too thick for the temperatures I used it in.
The example I gave of the Coyote V8 specified to run 5W-50 in the Boss 302. The Coyote has been around since it was first introduced in 2011, and I highly doubt the journal bearings are anything special as they can run anything from 5W-20 to 5W-50. The Shelby GT500 also called for 5W-50.Also 50 grade after adequate warmup is not excessively viscous for even under 0.0010 radial bearing clearances, though care is taken in how the oil is presented to the bearing through elliptical journal orifaces and other shell modifications. There has been much trial and error in the past before flow could be modeled with more widely available "affordable" supercomputers and associated software.

You forgot CAFE requirements.
So I made a phone call to get confirmation on this. Some of the teams will change to a lighter 0W-5 or SAE 0 oil just for qualifying. They put in a 0W-16 for actual race.
Well technically there is no SAE 0 grade right? Since there is no such grade defined by the SAE.
Those "thicky" NASCAR guys ...

. 138hp and a very responsive 6spd auto goes a long way in such a lightweight vehicle. The engine sounds like a rattle can on the specified 5w-20. It's nearly silent at idle on a 40 or 50, and much quieter and smoother at high RPM. Do what the engine doth protest the least is my motto. If I had a Toyota that purred like a kitten on 0w20, I'd probably stick to that.

Honda S2000. The 9.000 RPM F20C engine: Owner manual calls for 10w-30.
The last two reports of damged engine in the german S2000 Forum had two things in Comonn:
Trying to reach top speed on the autobahn and both engiens where filled with a 5W-50 Oil "For better protection".
Co-Worker is 100% Alfa Romeo fan. When he was younger, he followed advice from friends and used 10w-60 in his Alfa Romeo instead of -40 as recommended in the manual, because "These are such sporty engines, constantly high reving.." The engine had a Bearing failure in short time.
Since this time, he uses the Viscosity that the manaul calls and the engines last.
In the german Liqui Moly forum was a thread that looks like trolling: One guy has owned one Opel and two Skoda (=VW) , theses engines where specd for - 40 Oils or thinner. He reported that he used 10w-60 Oils for better protection becasue the engiens where "Tuned" and that he used the cars on short trips around town. All three engines died from bearing failure in short time.

And if they told you that wolverines made good house pets would you believe that too?
