My own current anecdotal experiences are 2 app 1/2 to 1 quart @ 14,000 miles, another 1 qt @ 5,000 miles, another 1/4 to 1/2 quart @ 20,000 miles and another 1/2 to .75 qt @ 25,000 miles.
Do I know what the consumption rates would be if I used conventional oil in place of synthetic? NO! Coincidently, I use the oem recommended appropriate Mobil One product. All but one present me with a catch 22.
So for example, if I am going to change the oil at 15,000 miles and it is 1/2 qt low, why should I top? If I am going to top, why should I change at 15,000 miles!?
This will probably freak the folks out who think 10,000 OCI's and above are voodoo at best, but indeed the topping recharges the additive mix.
Another example if you normally change oil at 9k, then why add? Just change. If you add, as you become more familiar with UOA's, you in effect can extend the OCI a min of whatever percentage 1 quart is of your total sump.
So for example my sump is 7 qts, so 1qt is 1/7= 14% So if I normally change at 15,000 miles, I can go 14% more (2,100 miles) longer and still achieve similar numbers.
I don't see much in print about extreme pressure, but it seems according to Vizard that it is the answer to less friction and wear.
Does this make sense? My 2004 Honda EX needs a boost something. Bill
just to call it snake oil.
Have you used this oil, or heard anything bad about it?
Being a retired engineer, I like to base my decisions on facts. Vizard made such a strong case for the importance of extreme pressure in motor oil. Bill
If indeed it does, it would probably cost more. Then of course, I would ask: does it now make (increase the chances of )my engine last/ing 2x longer (2x greater than 400,000 miles?) Can I double my OCI to say 40,000 miles, get X % better fuel mileage, etc, etc,.

Well I think even if you did, the real question is has it been tested with the current oil you now use. Chances are the answer is NO! Normally the cost benefit analysis makes "the product in question" BARELY justifiable. Most indicate no real advantage. I mean if you look at the benefits of a known product with known benefits(Mobil One synthetic) there is a very very low % who switch and a low overall percentage of folks that use it regularly.
Being an active engineer I have to ask, "Where's the beef?" If Vizard's tales of doom and gloom for all engines not running his super snake oil were true then no engine would make it past the 20,000 mile mark. To counter that point, I just tore down the top end of one of our engines due to a head gasket leak. The engine in question has been in service for eight years and has 143,625 miles on it, and has been oiled with Mobil 1 since about the 15,000 mile mark. So, what do you suppose I found inside?
- I found the valve train to be perfectly clean.
- I found the cylinder heads to be perfectly clean.
- I found the full compliment of honing marks on the cylinder walls still intact.
Specific to the high pressure areas:
- I found that the roller-cam followers showed no measurable wear.
- I found that the valve stems and heads showed no measurable wear.
Do you understand what I'm saying? No measurable wear after nearly 150,000 miles. Geez, at this rate, that engine will go an easy 500,000 miles. So, I have to ask again, "Where's the beef?"
While I have no idea who Mr. Vizard is, or what his credentials are, I will say this; from the sound of things, he's a snake oil salesman.

Here's a very interesting review of the claims for the extreme oil, from the Viper Club. Conclusion? They ain't buyin' it. Read it and make up your own mind. The reviewer seems to have given a very fair analysis but I don't have the technical expertise to double-check. But it sure makes sense what he says about it:

WAKE UP...to those that can't figure if going 100% Synthetic is right...YES...it is Right for all cars. Let's not forget the big picture - we're in an oil war!
We need to do every little thing we can in our lives to pass on a better world - if it's not too late.
I'm also not flushing my toilet for #1 either..he, he.
Barbie in Phoenix - 114 degrees today....another reason to switch out
Excellent reason to use synthetic, of course getting a few more mpg would do more good.
If it's yellow, let it mellow
If it's brown, flush it down.

thanks
The above has been repeated so often that it has become a factoid, or maybe an Old Wife's Tale, or maybe even an urban legend. The fact is that that advice is both incorrect and worthless. Then there is the fact that in 2003 (I think), VWoA retroactively changed the oil requirements for your car, and those oil requirements specify VW 502.00 for most of their gasoline powered cars, VW 503.01 for some of their highest performance gasoline engines (normally aspirated and blown), and 505.00 for most of their diesel offerings. What this means to you and your engine is that even though your engine most likely qualifies as needing only the lowest of these standards (i.e. 502.00), you should be using synthetic oil as all 502.00 certified oils are either Group III hydro-cracked synthetic or full Group IV PAO based synthetic.
In summary, changing to synthetic oil won't cause your engine to leak and is recommended by VW. As for which oils to use, ruking1's recommendation of Mobil 1 0W-40 is a good option, the oil is readily available at many/most NAPAs, Walmarts, Autozones, Mobil gas stations, and many other retailers.

For your car your best bet is probably Mobil 1 0W-20. Depending upon my next contract, a new Civic is definitely a possibility for me and the 0W-20 will absolutely be the oil I use in it. ;-)

It does, however, 0W-20 is simply a better 5W-20 (hence the fact that Honda is recommending it for their blown engines, not to mention the fact that Mobil 1 0W-20 exceeds virtually all of Honda's oil specifications for 5W-20). Basically 0W-20 and 5W-20 have virtually identical flow and protection properties when at operating temperatures, however, 0W-20 flows quicker following a cold start (i.e. before the oil has thinned) and as such, protects better when cold, especially up here where temperatures can reach well into the double digits below zero.
"I also thought y'all were moving to Hong Kong in the near future?"
Unfortunately the move to HK has become an "if" not a "when" deal. :-( As such I cannot simply stop working just because we don't know what the next six months have in store for us. We are all going over to HK as a family next month for kind of a "look-see" trip, and right about then we'll probably find out how big the "if" is (and possibly even answer the "when" part too).
I'll keep y'all posted.

At least in your own home...why the heck not. The home owner is saving on his water bill and helping the water shortage problem most everywhere that pops up one time or another. If a person MUST flush for #1....he/she is to anal for me.
I lived in northern California years ago and not flushing the "mellow yellow" was requested by the city of Santa Cruz and a way of life. I just continued this because it became a habit. Once out in the general public most people are offended if they're using the stall after me...I've had a few nasty looks in my day.
Synthetic Oil = Greener Oil
I believe that the synthetic oil producers have a hot marketing concept here....are you listening out there in cyberspace??

Our well is nearly 800 feet deep through solid granite. We pump it up, use it, and then give it back via our septic tank. Hmmm, no water rationing and still green too. ;-)

Even with the blurrieness of the picture (low light in my garage) one can clearly see the condition of the cylinder wall in the following picture.
FWIW, all but the first fifteen thousand miles or so have been run on Mobil 1. Initially I used 5W-30, and then switched to 0W-30 when it came out. I then switched again to 0W-40 when it became readily available and haven't looked back since. ;-)

I'll change my synthetic a little more often, thank you. 25000 miles is a little long to collect condensates and all the other side products in my motors in a climate that's cold 4 months of the year.
2014 Malibu 2LT, 2015 Cruze 2LT,
Anybody who runs any version of Amsoil for 25,000 miles is a fool. When you quote company propaganda like you are fond of doing all you are accomplishing is to degrade your own credibility. If you want to be a responsible member of this forum and still make such claims, please provide independent and verifiable scientific proof that Amsoil can run 25,000 mile and not have long since been completely exhausted. Better still, go over to BITOG and look at all of the UOAs for Amsoil's best oil that show that it's thoroughly useless by the 15,000 mile mark and then retract some of your ridiculous comments..
"Amsoil has been tested and has out performed Mobil One and because you dont have to change it as often it saves you money over a years time."
Tested by whom? Amsoil and their paid minions? Yeah, I'll believe them. NOT! After a couple of years of browsing through the UOA database over on BITOG I've come away with one inescapable conclusion, Amsoil is a good oil, but in no way shape or form a better oil than Mobil 1. As often as I see a particular grade of Amsoil beat that same grade of Mobil 1 (and not by much), I see the reverse where Mobil 1 beats Amsoil (and not by much again).
"You want to have less wear and keep your enging cooler so that your car will last longer go with Amsoil."
Uh-huh, prove it (and by that I don't mean spouting the standard Amsoil marketing bilge either).

We have a rule on solicitation here---if you see any blatant touting of a product for commercial gain, just let any Host know about it.
What ever little car tips I use that work out for the betterment of my car makes me proud so keep on tipping along. I'm a single woman and everyone knows how much we get taken advantage of in the car world.
I love this site and you guys are pretty cool and of course informative!!
