...no problems in [the] oil analysis at 20,000 miles. Universal averages show typical wear metals for this type engine after about 3,500 mile [of] oil use.

...we found no wear from [the] rings and nearly nil wear from [the] bearings.

The oil was a little light in viscosity, even from a 5w20, reading in the 10W range @ 210F. The TBN was 2.1 showing some active additive left.

Nice! For 5k miles on the oil, wear numbers are great. I'm loving all of these 20wt reports starting to trickle in.

quadrun1 · Jul 21, 2003

Great report! Civics really seem to like these thinner oils...

pscholte · Jul 21, 2003

You guys are better at interpreting these reports than me...we're OK with the viscosity since the oil is dino and had been in so long?

The low wear #'s are what really matter.

Obviously the amount of moly is being kind to the bearings.

timzak · Jul 21, 2003

Good to see a healthy dose of moly in the Exxon "cheapo" oil. I'd have my doubts, but the past 10K miles was Exxon, and prior to that, Valvoline 5w30 (which doesn't seem to have moly in it). So all the moly seems to be attributable to the Exxon.

Very good report especially after 5K miles, I was wondering how 5W-20 would stand up to the heat, (I assume this was just recently changed) although we are just now starting to see consistent 100's we have been pretty much mid 90's and rush hour in the afternoon with AC on has to be tough on the oil. I am now running pennzoil 5W-20 in my 02 Accord and will get it analyzed probably in September. Now if somebody from Phoenix would post a good UOA during the Summer, I would be totally convinced.

khager · Jul 21, 2003

Oh! one more thing isn't the Viscosity @ 210F 49.7 still in the 20W range? Thats what it looks like reading Bob's viscosity chart. Does anyone have a cheat sheet?

MNgopher · Jul 21, 2003

Nice! At 49.7 sus, thats roughly 7.1 cst. Still solidly in 20w land, although thinner than it started (the only 5w20 I know of that starts below 8.0 is Citgo Supergard at 7.8 cst).

Lots o moly, especially for a "cheap" oil.

No problems on these 5,000 miles!

Cutehumor · Jul 21, 2003

lots of moly there, is moly only in the Exxon 5w-20 weight? I'm running exxon superflo 10w30..on my first batch. I've done a similar move as the original poster. I went from valvoline (maxlife) to Exxon superflo, but different weights of course.

Does anybody know if this is the same oil as Mobil Drive Clean 5w-20? It performed very well.

MNgopher · Jul 21, 2003

Based on the information on the data sheets that I collected before choosing some to try, the Mobil Drive Clean and Exxon Superflo 5w20s look identical except Flashpoint - Mobil was 200 C, Exxon @ 224C.

Vis starts at 8.3 cst at 100C.

Pour point on each is -30C (-26F) which isn't all that great, but the Cold Crank simulator numbers and cold pump numbers are some of the best I've seen on a 5w20 (the CCS is better than that of Mobil 1 0w20!).

Oil was changed on 7/7. This oil had a 1.5 trips home (changed the oil while at home) which is 850 miles each way. Takes 12 hours, 7 hrs of 85 mph (4300ish rpms), couple hrs of 80 mph and 3 hrs of dodging cops and deer on 55 mph deserted 2 lanes where 62 is the limit.

Work at home so don't see much stop and go rush hour traffic.

New to the world of UOA but after seeing the moly comments realized that I forgot to state that the Valvoline was Max Life if that matters. Will edit the top post to reflect that.

Was leary of 5w20 (seems about as think as water) which is why I put in 5w30 but wanted to know how 5w20 would improve mpg and it did 1-2 mpg. Tested the second sample of 5w20 to minimize the effect of the 5w30 on the analysis. Thou after khager's comment wish I'd waited one more so the sample would've gone through the worst of summer.

Between Quicken & my mpg log here's a guessitmate of the oil change mileage and dates. Wasn't as close to 5,000/change as I thought.

code:

OEM Oil .............. 0- 3,900 11/04/02 - 12/14/02

Max Life 5w30 ... 3,900- 9,600 12/14 - 03/03/03

Exxon 5w20 ...... 9,600-14,400 03/03 - 04/26

Exxon 5w20 ..... 14,400-20,000 04/26 - 07/07

Edit: Guess I can't edit the original post so made Max Life bold in this post.

I believe the secret to your low wear is that you never let your oil go past 3 months. Nonetheless, I am quite impressed with this dino 5w20 performing so well considering the summer Texas heat gets hotter than Singapore! This Exxon superflo doesnt seem like ordinary dino at all, the flashpoints are all >220C.

Patman · Jul 21, 2003

Those who still don't believe a 5w20 can protect these small engines, take note of the extremely low bearing wear (lead) Very impressive!

nortones2 · Jul 21, 2003

Cerbera: interested in the results, but could you say what engine (type/capacity) is fitted and where car is made? UK built Civics have 10w/40 semi-synth recommendation from most dealers, and I think from Honda UK, with 12,500m change interval.

Bror Jace · Jul 21, 2003

Yes, another good showing for 5W20 motor oil.

With the flashpoints that different, I can't imagine this stuff is the same as Mobil 1 Drive Clean ... unless the Mobil specs are wrong or dated.

They sure put a lot of moly in this stuff, eh? About double a typical dino formula these days.

I wonder if the companies are taking a loss on this stuff to date? Loading up each batch with a pile of anti-wear but often charging the same price as 5W30, 10W30, etc ... They may be afraid of liability problems if they released an ultra-thin formula and it contributed to many engines' early demise.

Well, whatever works. :shug:

Good report!!

Mo and B workin'! (Ca, P and Zn too)

Is this a "hidden" group 3 oil??

nortones2 · Jul 22, 2003

Cerbera: thanks. I've got the 5 door 160hp also. Similar change intervals, but I'm still puzzled about the viscosity! Not that you're wrong, but exactly the same engine has disparate "recommendations" on viscosity. I can see why 5w-20 might help cold starts. I'd try it but not until the warranty is expired. No use asking customer service at Honda UK: all the brains are in Japan.
