I was reading about oil online when I came across a guy who has posted the following in another forum:

"0W-30 realy does not have very much long term use behind it. Personaly I will not use anything lighter than 10w30 unless the tempature is in the negative numbers with out windchill. I would never drive at highway speeds with 5w30 or lighter by choice. I belive that mobile-1 10w30 will flow and pump well bellow -30 degrees F so I can not see any reason to go thiner than 10w30. I have put too many miles on vechiles running 20W50 in the summer and 10W30 in the winter. I know their are some 5w30 and 0w30 Nazi's on this board but I have never seen a car make it 300,000 with 5w30 or 0w30. Most car that I work on that have been run on 5w30 are smokeing badly by 120,000 and have poor compression and consume a far amount of oil. The cars that have been run on 10w30, 30W,40W, 50W,60W and 20W50 have usualy faired much better. If clients are not running synthetic I normaly advise 40W,50W, or 20W50 for summer use and 10W30 for winter use. I have read the all of Amsoils info on 0w30 and Mobile-1's info as well and i am just not convinved yet"

What do you all think about his statement on longevity when 5w30 oil is used?
 
Doesn't sound like it's backed up by any good data. Just opinions.

Look at the newer vehicles that are spec'ing 0w-20. Wonder what he thinks about that.
 
Buster knows how to spell better than that!

That guy is a moron. Modern conventional 5w30s are more thermally stable than 10w30s of yesteryear.

The craap about 0w30 is totally ignorant, since 0w30 is always a synthetic - hence even more thermal stability and less breakdown than a conventional 10w30.

I have 225,000 miles on a vehicle using mostly conventional 5w30. IT'S NOT SMOKING, or consuming gobs of oil. It leaks a bit out the rear main seal but I seriously doubt running 10w30 would have prevented that...

Yeah, as soon as I got to that point, any credibility he may have had dropped to zero.

Brash and unsubstantiated observations based on personal opinions and such.

Just wait until the next ILSAC GF-5 comes on board in 2009 and the picture will be even more clear than ever, and all these "molasses" nazi who insisted in running syrups in their engine will have their say once again.

Oh and BTW: come check out our local taxi fleets (Bonnie, blacktop and yellow cab) are running 5W30 in their fleet of toyota camry/corolla taxis and a lot of them are still humming along fine as they reap up their mileage during daily activities, and no signs of bearing failures (cripes) nor any premature wear-n-tear reported in their mechanical maintenance reports.

Last but not least: there has been some serious engine design, metallurgy and manufacturing process improvements over the past 15+yrs and with that came motor oil of latest specifications (API SM/ILSAC GF-4) that catches up with the engine development and still be able to provide long and reliable service life.Hint: we don't use babbitt bearings in mass production engines anymore..

Bet ya this very same person/poster falls under the same groups where back in year 2K where they claimed that in about a few thousands of miles, those Honda engines running 5W20 is gonna ground to powder and moved to wreckers yard....guess whose laughing now...

Quest nails it. Individual experience is typically formed in a vacuum of your personal existence bubble. Stuff changes over time ..your limited exposure memory doesn't.


I too am waiting for the entire rolling fleet to come grinding to a halt in droves due to lighter grade oils.
 
Please tell us where this came from.

I guess this guy hasn't heard of products like GC, a 0w30 that's substantially "thicker" than most of the 10w30s out there. Not sure it will matter; I doubt this author will allow facts to get in the way of his opinions...
 
Oh yeah, I forgot to add that spelling "Mobil" (the oil company) "Mobile (the city in Alabama) is a sure symptom of terminal FOIS.*

*Fundamental Oil Ignorance Syndrome, sadly incurable in many who suffer from it. . .

EDIT: I'm sure our "North of the Border" friends would see that this is a prime case of "FOIS gras"! Sorry...

I believe I got this from a Dodge Dakota forum I came across while searching for topics on oil.
 
Reminds me of people like my dad. He's the best mechanic I know. Can fix anything, any model, any year... but thinks anything less than a 10w30 is 'too thin'. But, I thought the same thing until I found this site. But... I learned from him, lol.
 
If it is indeed that very same postings that came from dakota forums many moons ago then yes, that posting been out there since 2000/2001 and the poster has since seized to amuse people with his thoughts on his postings, and never provided any updates/response on the said subject matter.

Me? Dad's 7th gen civics still running on mixture of either 5W30/5W20 whenever comes on sale, bearings, UOA, etc, turned out nicely after 129,000kms to clock.

And in case you wonder: I'm currently running MC 5W20 in my fit and I intended to do so for the next 20+yrs to come. (80%highway mostly in PNW region)

So, my million $$ question is: where are those stockpiles of "ground to a halt" 5W20 civics in the wreckers now? If so, where?

There due any day now, Quest. All of a sudden, just like the Martian invaders in War of the Worlds ..the infection that lighter oils have been insidiously cultivating over the past 6 years will suddenly strike them down. Just a large segment of the rolling fleet will ..just stop.

It's just a matter of time...
