The test data on the rightmost was 3000 miles on
Mobil synthetic blend 5-30.

The new test data on the left is 5750 miles on the
Amsoil Series 2000 5-30.

I didn't send in the redline sample for oil test.

The oil is reaching the upper range of viscosity so I'll drain it soon at 7k miles.
It is just turning dark now.

The wear metals at 5750 miles are same level as the mobil was at 3 k miles.

The mpg dropped 1 mpg at one time, I took two mpg records and then found it was the rear tire alignment from the ingalls camber kit problem.
The mpg is staying around 25 to 25.5 mpg now, I can get it to 26.5 if I try( hard to do for a whole tank) but can't get it less than 24 driving hard.
This is zero highway.
Before amsoil i was always around 21, some alarming tests under 20.

Long term it has been a 12-15% fuel savings.

I am running 5-20 XL7500 in the other honda. That car is never here and
I can't get mpg record and it is 90% highway. In time I'll get the XL7500 in
the other accord and get local mpg record. I have enough series 2000 for
the next TSX oil change so won't test the XL7500 in the TSX this year.

These are the descriptions of the test elements, linked above.

I was motivated to run the XL7500 in the 2004 accord LX 2dr because
I didn't like the engine idle and low end smoothness. The car was home last
weekend and the engine felt better and smoother. Since amsoil often runs
heavy viscosity range, this XL7500 at much lower cost may be sutiable
for the TSX at 5-20 weight, at least in the winter, providing it is as good mpg.
I won't get to test the xl7500 in the TSX until next winter.

Are these Blackstone people crazy, they hinted for me to send in another
$20 sample in 1250 miles. I'll just change it.

So which type of Amoil is recomended for the TSX, as there are alot of flavors.

 

I run the 0W-30 Series 2000 that TSXTuner tested above. He calls it a 5W-30, because that's really what it is, it just has a very nonlinear temperature-viscosity relationship that makes it act like a 0-weight during startup.

I saw noticeable fuel economy improvements (32-34 MPG on highway trips, versus 30-32 on dino oil), although I switched to summer tires at the same time I switched to the Amsoil, so it may be even better.

I want to see Sauceman try some of this oil. I bet he'd break his personal MPG record.

 

BTW, how much does an oil analysis like that cost? If it's reasonable (<$75), then it is probably worth doing every year or so to make sure you aren't experiencing severe wear.

 

$20 per analysis.

 

Anyone know if there are any Canadian companies that do this? I'd be interested, but not if I have to send "hazardous materials" across the border. I know that won't go over well.

 

Sorry that was a mistype, the series 2000 comes in 0W-30.

There is a much more affordable amsoil XL7500 ( rated for 7500 miles )
that comes in 5-20 that may be suitable for the TSX because
amsoil runs at the heavy side of viscosity range.

In the first benchmark test on mobil 5-30, blackstone said it was at the low end of range and almost a 5-20 oil. So is there a viscosity difference in
amsoil 5-20 and mobil 5-30, probably not. I bet XL7500 5-20 is fine in the TSX.

There are cheaper oil test services, maybe $10-15. I was only doing these
two tests so costs weren't going to add up and I went with Blackstone.
It's convenient because they send the sample and mailing package free.

Also my oil filter and CAI filter are K&N, air last cleaned about
10k miles ago and 33,000 total age. Both performing well.

Another guy informed me of a military product that is a metal conditioner.
He said he had to turn down his engine idle speed 200 rpm after adding the
stuff. But i'm skeptical of these things.

 

For my last oil change, I picked up 5 quarts of Redline.


It did absolutely nothing to my MPG.

 

Curls- sending oil in the mail is not considered hazardous in the U.S. For $10 more you can have the TBN checked.

 

Somebody loves their car! Cool test. Thanks for the info.

 

Hope it helps. The expense of amsoil is easily justified with
mpg and oil test results. It may be possible to get similar results
from the XL7500 and at a lower price than mobil 1. With the viscosity
issue it is unknown if series 2000 should be run up to 10k without
another oil test. I will probably just change at 7-8k depending
on season.

We also needed to see the K&N CAI filter results. Low silicon is good news.

The only way to verify the mpg is to go back to conventional oil
one time which I may do.
Nevertheless, the oil test and wear are enough to justify the oil. The
mpg is real, I only got one reading over 24 mpg in the first 30k miles
of the car's life and mostly under 22. Now always over 24.5. I'm being
conscience of it now which is difficult to factor out but I'm certain I tried hard
to get good mpg before and could not.

I picked up 1.5 mpg going to redline and that could have been
other factors, cleaned CAI filter and installed voltage regulator
at same time. And maybe just being conscience of it. I was not attempting
to study mpg at that time. I just tried the redline because it was on sale.

At the change from redline to amsoil there weren't any other
contributing factors and i was purposely studying the mpg, I
was trying to get best mpg on the final tests of redline, then amsoil
kicked in with a significant 2 mpg improvement over redline.

Otherwise I though redline was a good oil and the engine felt better
with it, but amsoil proved better based on mpg.
