5W20 vs 5W30 in the Midwest for a car that frequently takes long trips

I’ve read that newer API rated diesel oils are the equivalent of Euro A3/B4. That’s the story behind the story.

I'd like to see some doc's on this.

Yeah, I seen it on BITOG a few years or so ago when a few in my circle were sourcing alternative oils for their EcoBoost F-150s
Citigo Citguard 1000 5W-40 turned out to be an awesome choice.
Citgo has their own additive division so during the “Supply Disruption” Citgo blending and distribution was unaffected.
It wasn’t to long ago the API or EPA forced the removal of dual rated diesel oil. Gone is CK/SN+ or whatever the dual ratings were labeled as.

Motorcraft oil sucks for protection. It shears down fast.

From some industry leaders the oil additives have gone up 100% and oil prices for engine oil have remained the same. I wonder if quality has gone down?

It certainly has, most of the "premium" shelf oils switched to cheaper base stocks to reduce costs since the big C. I don't really think it matters that much though, as long as it can meet the API specs it's fine. Especially for those of us on here that change every 3-5k miles, lol.

My understanding is GM also recommends Mobil 0W-40 ESP for track use.
0W oils most always have a higher percentage PAO base oil than 5W-10W.

Had to look that one up "Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. These synthetic hydrocarbons are designed to provide superior lubrication performance over a wider operating-temperature range than petroleum oils and typically are less volatile."
Perhaps why many European automakers recommend 0w. Mercedes-Benz, Porsche and Volkswagen.

I use LiquiMoly 10-60 in my HD. But I ride when most would say it's too cold.

My 91 FXRS and 2002 FXSTD were on the road in south Florida. My coldest start up was at Daytona bike week.

PAO = Group V
The boutique blenders have typically gravitated to using a higher percentage of group V in their base stock blend. ie; Liqui-Moly, Amsoil, RedLine, Motul…..
For retail off the shelve non-dealer or members only available oil the 0W-XX is the most easy and affordable way to get a boutique oil base stock blend at a local retailer.

PAO = Group IIII
The boutique blenders have typically gravitated to using a higher percentage of group IIII in their base stock blend. ie; Liqui-Moly, Amsoil, RedLine, Motul…..

Not finding a difference between 0w and 5w relative to PAO base.

"Mobil 1 is made using the highest grade base stocks – Group IV/V PAO/Esters – combined with proprietary additive packages that deliver far greater protection than competitive full synthetic motor oils".

Not finding a difference between 0w and 5w relative to PAO base.

You’ll need to find and open the SDS/MSDS sheet for the oil you’re comparing. There you’ll find the percentage for the base oil “CAS” chemical abstracts service.

My FXDWG is my avatar, I ride if there is no ice on the roads.

Hence the K4-FXD, I should have put a - when I signed up.
