And the marketing efforts aren't hurt by that LOUD orange filter color either eh?

Yesterday it was 104 in Sacramento and during the highest temperature of the day, I sat in my car for approximately 30 minutes for my evening meal and to read the paper. The car was idling with the A/C (and cooling fans)on for the entire period. When I was finished, I glanced at the Temp. gauge. The gauge had actually moved one or two "clicks" to the left (cooler). That, in a nutshell is the most convincing reason for me to use synthetic oil. To me, oil performance during northern California's hot summers is the most critical benchmark. Mobil-1 has never, ever failed to protect the engine during the summer months. Just my opinion.
So, car runs warm and in VA it gets hot. This has not had a bad effect on engine. Can anything be attributed to synthetic oil. I don't know. Above poster uses Militic. Does it work. Don't know unless more people try it. It seems though that most people posting here and on Bob's are basically happy with whatever oil they are using. Maybe that is why the # of posts have decreased, people realize it just does not seem to matter much.
Also posting my Toyota results if anyone cares. All reports on Toyota are Amsoil 10W30 with Amsoil filters.

Now even though I don't use synthetic, I would think that the syn. would provide some extra protection were the cooling fan to fail, but with a functioning cooling fan and adequate coolant idling all day shouldn't be a problem.
Actually the extended idling question was posed to Click and Clack a couple of weeks ago. Their answer was that idling was no harder than driving slow, and driving slow was no harder on an engine than driving at normal speeds.
What is up with this new "Higher Mileage Formula" and "New Car Formula". I used 10W30 last time and this time I can only find the 10W30 in the higher mileage formula. The new car formula is the 5W30 version. I have a 2002 QX4. Can I not use 10W30 Mobil1 full synthetic in a new car? This seems strange.
Excuse me while I run for cover... >:oÞ
FYI the Mobil 1 ATF I wanted was the exact same price. Now AutoZone used to price these around $26 a 6 pack - so it's not just Mobil's synth Oil going up - ATF too.
Now I just paid 21.99 a case (i.e. $3.66 a bottle) at Costco - think I'll truck down and get some more if it's still there.
BTW the VAN drives great so far with the new SL product - just did a 800 mile roundtrip to Syracuse in 90+ heat with 25 mpg while running the A/C. Heat gauge didn't budge. Does seem a tad slower to accelerate though.
Lastly, as for board traffic - it always goes down in the summer - I see this with all the boards I scan (Bob's, Edmunds, Autotopia) as well as EBAY. After all, driving's fun but I'd rather be driving a Titleist!
One 4.6L V-8 at 30k miles using Mobile One 100% of the time vs. another 4.6L V-8 that used Castroil dino for 30k miles and then Castroil Syn for its last 10k miles after it changed hands.

Conclusion(?): The newer Mustang has one cleaner rocker cover than the older Mustang.
Unless you are the one that gets stuck scrapping the crap out!!? I take it you have never done that!!!
Another good reason not to use Castrol eh?
Oh, I agree that cleaning the rocker covers is less than fun. I would also consider that the stained cover probably came from an engine that did not get frequent enough of oil changes, while the cleaner one did. What do you suppose?
Add to that high performance jet engines (F-4E, B-52's, KC-135's etc).
In that sense, I am the wrong one to ask for I had a vehicle with 250k miles using 15k synthetic oil change intervals that looked like the clean one that was posted. So if it is a question of conventional oil change intervals, I would guess than you have to change the conventional oil NTE 3000 miles. But i might add that most conventional oil manufacturers DO NOT expect folks to look at their engine innards like this mustang guy has posted.
The other thing as you well know, is that the engine will run quite nicely with 3-5 more pounds of sludge in it. So in that sense it really doesnt matter. From that perspective, I totally understand why folks that use conventional oil do not see fit to use or want to switch to synthetic oil. Me? I just really like a spanking clean engine whether or not I look at it or not. For example I will not tear down my Corvette Z06 engine just to look at spanking clean engine innards if I dont have to.
Any thoughts?
tkenny, apparently Amsoil has changed formula on their 'low end' oil, it's not a full synthetic but remains at full synthetic price.
I have to tell you I bought 18 qts of Mobil 1 at Costco on Friday. Not to worry though, I haven't gone over to the dark side, just making a purchase for a few friends.
Fleetwood, my new brand of choice,Chevron Supreme, has been completely sold out at Wallyworld. Please stop telling people about it!
I'm a Mobil-1 10w30 user now, and have always been. On my high-revving Honda engine I'd really like to see less drama when you go past 5000rpm... And seems like if those claims about Royal Purple are true...
So... did anyone try it?

Thanks for the help.
Texaco makes Havoline. Chevron makes Chevron. The company is on the NYSE as ChevronTexaco.
Car: 1997 Subaru 2.2L driven almost exclusively to and from work which is an 80 mile round drip, 70 of which is on the freeway.
Oil: Amsoil 5w-30 ( the '25,000 mile' flavor, not the '7,500 mile' kind ). The oil had about 5,200 miles on it. Filter was a purolator pure one. Analysis also done by Amsoil.
Glycol: neg
% water: < 0.05
% fuel: < 1.0
viscosity @ 100 C: 11.0
% solids: tr

tbn: 7.0
Fe: 8

Na: 3
Mg: 396
Ca: 3162
Ba: 0
P: 1226
Zn: 1529
Mo, Ti, V, and Cd all zero.
I'm encouraged by the iron and lead numbers. The ones I'm not sure of are aluminum and silicon, and I'm ASSUMING the mg, ca, p, and zn are coming from the oil, not my engine.
My next drain I think I'll go 7,000 miles and try this again.
Any thoughts? Comments?

The %oxd is the percentage of oil oxidation. The %nox is the percentage nitration which is a measure of the acidic buildip in the oil (I believe)
I would recommend that you check out this site:

You will get your questions answered there This board has become somewhat stagnent, as you can see.
The TBN (ability of oil to neutralize acid) at 7 is okay but to me indicates that there is no way this oil could go 25,000 miles. The rule of thumb is that when TBN gets to be 50% of original value or 2 the oil needs to be changed. This oil started out around 11 or 12 and at 5000 miles is down to 7. If the same degradation continued it would need to be changed well before 25,000 miles. Of course that is one year or 25,000 for Amsoil with a filter mandatory at 6 months. Aluminum is fine.
Remember, this is trend analysis one sample does not tell you much. Oxidation and nitration are okay, don't remember if the concern begins over 50% on these or not. Lab obviously said oil good fgor continued use. The most I can go on Amsoil is 12,000 miles before my silicon goes through the roof. True on all of my cars.
I think your analysis looks good.
Analysts Inc used to do the analysis for Amsoil until about 3-5 years ago when Amsoil started its own lab. I use Analysts Inc and have since early 90s but they are no longer affiliated with Amsoil in any way.
