Lets see the math.
3500/20= 175 G. 3500/21= 167 G.


You'd have to show me every tank of gas calculated perfectly with 3 consecutive runs of the same conventional oil and 3 consecutive runs of the same synthetic for me to believe oil of the same viscosity would give you a tenth of a mpg, let alone 1 or 2. Oh, and you'd have to monitor tire pressures at each fuel up as well, along with other variables (of which there are many) that affect fuel mileage. Just :2cents:

No,thank you.


Its easy to write something on a board but hard to have actual data.

The problem is there are people here who have done the work THEN post.

Then there are people who just post.

We know Bob is one.

Which one FZ1 are you?

Take care, bill




Cmon now bill. Let's not get all contemptuous here. I thought you'd be able to handle being wrong. I guess not.

Just kidding bill. Please take a break and grow some thicker skin and then you can come out and play some more.

As far as mpg and synth oil goes, Audi & Castrol test found 2% better mpg on German Syntec SLX 0w-30 over 15w-40 HDEO.

But how much of that 2% is due to it being synthetic and how much due to it being a 0W30 vs a 15W40?

If there was a 2% improvement using a 0W30 over a 5W30 conventional it would be more meaningful.

Fill it with dino 15w-40 oil. Drive it and record fuel economy.
Next OCI, fill it with synth 5w-20. Drive it and record the fuel economy. I assure you that you will see a difference in fuel economy just due to viscosity differences. Collapse the view as you compress the visc differences.

You can come up with any objection you please ..someone with this engine (any engine) will be in a cold enough environment to make whatever the spec'd oil is resemble a 15w-40 (someone in Canada, perhaps) ..and someone somewhere will have a sub warm up visc that resembles 5w20 ..so state your objections carefully ..that should pretty much cover them

Don't know what the Pilot would do with those oils but with the majority of the wife's trips less than 3 miles and using a synth 0W-20 it is only averaging 13-14 mpg.


Do it with 15w-40 in the summer (hmm..that's now). I'm sure that it's not anywhere near what a 0w-20 is @ -35F. Compare.

I have tried synthetic. No apparent difference in MPG. Gary I understand your point. I live in Texas my start up temps are usually in the 70-s to 100°f. My 5w30 and 5w20 Dino oils are not going to have a significant difference in viscosity compared to a Synthetic. I agree in cold temperatures such as in Canada or Alaska synthetic is preferable for winter start up.

When someone pours expensive engine oil in their crankcase they are going to want to notice a difference. Sort of like if you tell everyone that Mobil 1 is noisy they will start to hear a tick..Perceptions are easily influenced by expectations. Perceptions however are not measurable. The opinions referred to in such cases are purely anecdotal. Nice stories, great marketing and good to influence the perceptions of others. These are not measurable improvements.
Marketing related evedence is, as a rule, always questionable. The only reliable evidence is from non oil marketing labs and by detailed persons who keep records and notes on vehicle performance. Excluding marketing I challenge you to find convincing evidence to support your perception of synthetic being superior.

I will agree with you that Amsoil is an excellent oil, no doubt about it, but I must also say that I have never seen a million mile gasoline engine run on Amsoil, but I have seen a few on Pennzoil, and with out any of that nasty sludge problem.


Johnny, I believe Mobil did though, if I remember correctly? It was an Audio or Saab engine I THINK and they ran it for the "equivalent" of a million miles, changing the oil at 12K mile intervals I THINK and the engine was torn down after the "million mile run" and the bearings and other associated "wear parts" were all within spec for being brand new.

This used to be on their website.


Yes, I believe you are correct about Mobil doing this controlled test. I think it was with BMW, but not sure.

Yup, when you have no FACTS to back up your claim, you call your opponent "contemptuous" (which is bizarre in it's own right)...Thought you'd be able to throw out facts backing up your claims without calling dissenters contemptuous. ( OOPS) ...

Keep diggin builder...

FACTS: FACTS: Still waiting on the additives in Amsoil..........let me rephrase that: the "LACKING ADDITIVES IN CONVENTIONAL OIL (or heck, synthetic blend or over the counter synthetic oil

) "
"THAT REDUCE ENGINE WEAR"

That sounds about right. From what I can determine, differences in efficiency between oils that you would likely use in a given engine (in other words, oils of the same or similar viscosities) are usually on the order of 1% or less. A 3% difference between two oils would be huge, and a 2% difference sounds about right for oils that are of such differing grades as 0W-30 and 15W-40.

We should be talking, in general, about differences of about a percent or less, or 0.2mpg on a 20mpg car. Anybody reporting much more than that most likely has some error or uncontrolled variable in their data, which could easily have to do with tire wear, tire choice, weather, differences in driving between one OCI and another, and so many other things.

I do not believe there is a practical efficiency difference between synthetic and conventional oils of the same grade. It is possible that, by using a synthetic with superior properties, one could successfully switch to a lighter grade and receive some benefit from that - again, perhaps around 1% or so.

The Earth is round tidbit. Yup, no facts poignant to the assertion at hand. My buttt is round...

 

[Drew99GT]

And by the way Bob. this is all based on "We need to remind folks that the best oil should always be used and rightly so".

Hmmmmm. Are you by any chance being a tad facetious here? I'll hold back with the sarcastic rhetoric until which time it seems appropriate to respond.

PS. Whats wrong with my commenting from real life experience when you seem to be commenting from seat of the pants experience?

 

[Gary Allan]

Isn't the seat of your pants founded somewhere in "real life"

(die thread die).

 

[Bob The Builder]

It was a facetious comment. I guess most of you guys are well over 50 years old. You sound like old fogeys...always needing everything explained to you in minute detail before you understand anything. Geez. Get over it. It's only oil.

That I can agree with.

So don't waste money!

Still no facts to back up your opinion, unless you cede the floor?

World-wide.

Oh my gosh. Absolutely not. I refuse to give ground here. Cheap oil should all be poured down the drain....or relegated to 2 qt per day oil burners.

 

[FZ1]

I'm sorry I noticed the increase in mpg.Lol.

 

[Audi Junkie]

I think the test I refered to is valid since the two oils share the same HT/HS. iirc, Mobil claims a similar number with the AFEs vs dino (probally 10w-30).

I respect people here that make assertions........AND BACK THEM UP WITH FACTS. Bill in Utah at the front of the line.

As it's been stated by the protagonist, we're here to help the people...
