Dino vs Synth question

Paulinfiji, I think your maintenance program is par excellance. I feel you could give advice to many of the people on BITOG. I agree with everything you are currently doing. Since Hondas have such a small sump, how much money would you save by switching? Amsoil is a proven performer in harsh winter environments.

With increased perception of valvetrain and other noise and the tendency for M1 to show relatively higher levels of iron, I don't see how you can make such a definitve statement. Sounds like an opinion to me.
 
I don't think I ever said oil X wouldn't sound louder in engine A vs. oil Y. Engines do sound different with different oils. I know my wife's Volvo 850 is just plain more quiet with FRESH oil. Mainly it's a viscosity and to some extent an additive thing.

But again a general statement such as "synthetic oil is louder in all engines than dino oil" is really not true. I am NOT disregarding the numerous folks who report M1 being louder. But is this really a base oil origin cause or a viscosity issue? Most folks using Amsoil, Redline, Schaeffer's say their engines are a tad quieter.

Not only is my engine quieter but the oil stays cleaner longer. At 3K the oil looks honey color with amsoil 5W30. When i bought my 2002 Tacoma i bought that crappy prepaid maintence crap till 55K. During that time i was using redline till recently i switched to amsoil 5w30 all i can say i wished i swithced sooner. Ive got one more oil change left and then its all me after that. Amsoil is buy far the best product ive used.
 
I'd stick with dino unless your doing extended drain intervals, UOA's have shown that dinos can protect engines as well as synthetics under normal drain intervals. Using synthetics is a great idea, but a complete waste if your going to dump them after 3000 miles.

No.

Your idle speed will increase.

It will increase just as it does anytime you go from a relatively thick oil to a relatively thin oil.


Your idle speed, redline speed or any other engine speed won't increase/decrease with viscosity.
The engine idle/rpm speed is programmed into the engine's computer, so it will always make necessary adjustments to keep the rpms in the same exact range regardless of the variations in the oil's thikness or amount of drug it creates.

This statement proves my point that other people have, and can support, their own opinions.
Nope.

We all have access to the UOAs, which are not opinion.

If there is a "tendency" or "trend" it would be supported by references to the UOAs which demonstrate that trend, advocates of Mobil 1 would cease to post, and ExxonMobil would be reformulating Mobil 1.

I agree. Use what the auto manufacturer recommends. The use of synthetic oil in an engine not designed for it is a waste of money. And, changing synthetic every 3000 miles is a colossal waste of money. It still amazes me the number of forum members who change their synthetic oil every 3000 miles.

Perhaps on some of the newer electonically controlled vehicles you're correct, but years of experience with carbureted engines from single to sixteen cylindered, and many injected vehicles, indicate otherwise.

It's simple physics. The heavier the viscosity, the greater the friction.

Better call the geeksquad and tell them to reformulate Mobil 1. I get 88 hits by searching for "Mobil high iron".

I don't need to provide any references. I am not the one making any bold claims.
 
I maintain my wife's 2003 Accord which we purchased new. I have changed the oil at 5K intervals since new. At 5k I began using Mobil 1 0w20 and puralater pureone filters.I tried just changing the filter and adding 1/2 qt at 35k. At 250 miles later I checked the oil and found it to be black as coal so at that moment I said to **** with Mobil 1 and changed to Motorcraft 5w20 blend which is less than half the cost of M1. If you plan on 5k oil and filter changes a blend will be just fine.

Hundreds of subscribers are posting the results of UOAs. A good portion of them are using Mobil 1. They're reading the other UOAs and keep using Mobil 1.

The bold claim appears to be that everyone missed the fact that Mobil 1 causes engine wear.

The old saying is that you can't prove a negative, and in this case it would require assembling every UOA, grouping them by brand, and then using some statistical analytical method to determine if on average engine-by-engine Mobil 1 shows higher iron numbers.

Apparently you haven't done it.

That means the notion that Mobil 1 shows on average higher iron numbers is an unsupported bold claim.

Black oil doesn't really mean anything without an oil analysis.

You can get black oil switching from an oil that isn't doing much of a cleaning job to one that does, which immediately purges all the gunk out into the new oil.

There is a difference between perception"high iron" and numbers The search querry means nothing without the content and circumstance that resulted in a hit on a search, Pull the numbers on like engines and crunch them. Feel free to crunch numbers as you wish using the vast data base on this forum and you will see that the numbers are not bad. I already did enough to feel comfortable with M1.
Here is the link with the data I wasn't to lazy to put together to get a picture .

'

ExxonMobil has billions of miles on test vehicles to demonstrate that Mobil 1 holds it own against the other synthetic basestock motor oils.

I have seen no tendency for Mobil 1 to show relatively higher levels of iron in UOAs on this board and elswhere in sustained use.

The perception of valvetrain noise is completely subjective and unless it's correlated to something that can be measured I'd consider it to be as reliable as the perception that an engine is "peppier" using Splitfire spark plugs or Slick 50.

Me personally, I'm pretty cool with my engine going tat-tat-tat-tat-tat, but when mobil 1 makes it go CLACK CLACK CLACK CLACK CLACK, I sort of DO begin to worry about engine wear.

The only reason why the sound of engine using Mobil 1 would change from the sound using another oil is viscosity.

Mobil 1 is on the low end of any viscosity standard.

Whenever i used syntetics even a group 3 ,the

Currently i am using a semi and i don't intend to go synthetics again in my daewoo.
