Oil Suggestions .

[Paulaurora]

Hey everyone. Some of you know that my daily driver now is a Volvo . Volvo manual saying to use 5w30 oil or 0w30 oil in extreme conditions . 2 weeks ago Volvo turns around and saying that all cars with the new engine (2017-2020) need to use oil 0w20. What you guys think of that is that to kill ur engine faster or opposite? Will it benefit my aurora to use 0w20?Please let me know what you guys think about all this. Thank you.

Corporate Average Fuel Economy (CAFE) standards...

I don't think Volvo is trying to kill engines, just trying to get fuel economy numbers up. A thinner oil may only give you .1 better MPG, but multiplied by the number of passenger cars they import, it adds up.

Our Auroras are pushing 20 yewrs old, I'd stick with the 5W30, haha!

Thanks Tigger for your input .

IMHO......stick with the 5W-30.

Walmart 10w40 In The Summertime; keeps those annoying oil leaks under the perceived semblance of control.

I went looking for Valvoline 0w30 for my F150 (it's recommended for Ecoboosts), couldn't find it for less than 2x what I normally pay for 5w30 --& so, I didn't make the change.

I run Castrol in my SVT Focus. It's older (2003 versus 2011 truck) & I've seen no one recommend 0w30 for it, but Castrol 0w30 "high mileage" is the same price as 5w or 10w30, so I switched the car over.

It runs just fine, no obvious leaks. My research said that the number before the "w" describes how it flows, when cold, most engines warm up in less than 6-7 minutes, and after that, anything "____w30" should run exactly the same... The only indicated down-side was that there may be more piston blow-by with 0w --but again, that should only be at/near startup.

I have only run it for 1000 miles or so now, so I'm still looking for problems or results. The car has 120k miles and has been on full synthetic at least the last 60k miles.

The only thing that I have seen no one pushing 0w is: it's harder to read the dipstick. The oil is so thin (like water), it can be hard to find that oil level. I'm pretty sure I went 1/2 quart over, because it looked like there was nothing on the dipstick, so I added another 1-1.5 quarts.

I've always liked about full synthetic: it seems to leave a pretty good "skim" of oil on surfaces, for start-up. I really couldn't tell you, if the 0w does as well at that.

When I tried full synthetic in my aurora, I immediately started getting "low oil pressure" warnings. I had to go back to traditional & add a quart or 2 or heavier weight, to stop the warning messages.

The odd thing about my Ecoboost, the oil-fill cap always has a dolop of oil about the constancy of thin peanut butter, on the inside. I don't know if that's condensation, to do with the high pressure, or the engine just whips it up like that.

I have seen that in testing, Valvoline has more oil "boil off," under high heat, than some other brands. I have always used Castrol. I'm using Valvoline in my Ecoboost, because it's my 1st turbocharged engine, and I bought it from a Master mechanic who assured me that the oil was the best available, for that engine.

...This is all just trivia, anecdotes, and my opinion, but I hope it helps.
