5w20 or 5w30? Which do I run and why. Is 5w20 a hoax for fuel milage?

[aciddiver]

On my car, it says 0-20 on the oil cap. When i use that, the car burns oil. In the manual there are 3 options, 0-20, 0-30 and 5-30. Now i use 5-30 dexos1 gen2. No oil consumption, no problem.

I’m In the oil industry. The thinner oils are for fuel economy only. All of these energy saving oils will not meet European specs for sheer. I run Castrol Edge Euro 0w-40 in my 5.0. Gives solid cold flow and the 40 is on the lighter end of the spectrum and gives you plenty of protection at higher temps. The 5w-20 is a 20 at 212 degrees. If you are working a vehicle hard and the temps are over 212 you no longer have a 20w. I’d always recommend going up a weight. Won’t hurt the engine at all. The lighter oils on the cape and manuals are “recommended “ not “required” for vehicle operation.

I think you summed it up well. Regular cars can run 0w-20 all day long because it's never at sustained high load and cylinder temps. High performance forced induction cars, trucks and tractors tend to need the thicker oil to maintain the film and oil pressure. What tends to kill regular cars is simply neglect, not the oil itself.

Protection over fuel economy. The decision shouldn't be too difficult.

I been running Mobil 1 5w30 for years in my 2003 cobra. I had a mechanic that builds mod motors tell me 20w wasn't thick enough. Makes sense with all the heat.

[santosperez]

I’m glad you made this vid as I too wondered about using 5w30 instead of 5w20

[arthursmith]

If you have high mileage like over one hundred thousand miles you can go up in viscosity. Instead of 5/20 go 5/30.

Excellent illustration of how B.S. CAFE standards altered oil recommendations on these cars, even when the engine design never changed. Ever since i watched a FordTechMakuloco video where he mentioned he uses only synthetic 5W30 in all the 5.4 3V motors he works on i have never gone back to 5w20. I dont baby either of my cars so it gives me peace of mind to know my oil can handle the abuse.

[timwynn]

09 Toyota Prado, book says 5w 30, but now using full synthetic 5w 40, much smoother than 30, and I live in a hot tropical climate in Asia where temps don't dip below 30C/88F, so a bit thicker oil makes more sense.

I did a ton of research on this, I run 10w30 with mmo in my 2.4l jeep. Calls for 5w20. Great video love oil talk, everyone's got their own flavor and weight... catch can anyone?

[grampy]

I have a 2010 Honda Element that calls for 5w20 on the cap but i have only used that twice. Didn't notice any difference in fuel mileage with the 5w30. I looked at what same engine called for in Japan and it listed several weights to use depending on the temp. I normally use Pennzoil Platinum but recently started using Pennzoil Euro changing around 5000 miles. It has 148K on it still running like new with no oil use. The car companies don't want your engine to last for a long time they just want it to get past the warranty then it's all on you

[stevel]

An article by a Lube magazine said 30W is optimal viscosity for an engine. Also they said Ford trucks in in North America use 20W, but in Europe, Ford trucks use 30W to comply with factory warranties.

[michaelmurphy]

I worked for Pennzoil branded products when they were in Oil City, PA. It was 100% PA Crude back then. These Oils are both 5W oils, The companies add viscosity index improvers to make the oil act as a heaver weight oil when needed. As the engine heat rises, the oils have the same viscosity as a 20 or 30 weight. From what I understand the oil will break down as the heat affects the engine. Change your oil within 5k miles, for extended life of your vehicle. Also Check your oil once a month, you can lose oil without seeing it dripping. Hyundai especially.

I agree with your also agree with RIGHTEOUS comment climate is something to consider, I live in Houston/Tx and here the summer is HOT so I do use 5w-30 (not 5w-20) if I was is a place that is really cool (below or at 0) I will go with thinner oil for sure, Also there are Engines that You need to follow the OEM Recommendation because the CHANNEL of the oil (the Lifters in this case and ) in some places of the engine is so small that a Thinner oil is needed for better lubrication an example is the DODGE Challenger with HEMI V8 engine. Thanks for your video.

[righteousredneck]

Climate is also something to take into consideration. I ive close to Houston and our summers are brutal hot. I run 5w 30 because of the better protection in the heat. I may get slightly worse fuel mileage, but I feel in the heat the added weight is better in hot conditions than the thinner 20 weight. I might not get as good of a flow rate, but as hot as it gets here in the summer..I believe it's the better choice in the summer months

[mooosestang]

I've run 5w30 for the entire life of my 06 mustang gt, but i can't help but think we should all still be running 10w30 unless you live in the Northern most points of the globe.

[davidmckinney]

Thanks buddy for the video I just picked up a oil change for my 04 Ford f150 4.6 and I got 5w-30 👌instead of 5w-20.

[Shin-kfux]

Bro love this vid. You explained things simply and not with all this other bs about products and sh*t like most of vids ive seen. Ty!

[samaccurso]

My everyday driver is a 98' lexus gs400, live in South Florida, I've always run 5w30 as factory recommended, car drives great with almost $230k miles on odometer.

[martinschulz]

Great video. I've heard Ford Mechanics say to run 5/30 and not the Ford recommended 5/20 because of Cam phaser issues that the thinner oil causes.
