RLI BioSyn 0W20 10,250 Honda V6

[TrailRunner]

RLI BioSyn 0W20
10,250 miles on oil
2004 Honda Odyssey 3.5L with 82,500 miles

Good results with RLI. Even better than with Schaeffer Oil 7000 Supreme 5W20, although this drain interval was a 1/3rd longer. Viscosity is right on spec for oil - no change at all. No oil was added and no oil was consumed over 10,250 drain interval. Main problem is fuel dilution with the 2004 Honda V6 3.5L; Fuel dilution was 1.45%. I am very pleased with the results with the interpretation by Terry Dyson (NFI).

Looks really good! I assume it's ok that TAN > TBN?

 

[benjamming]

buster,
it can be

TR,
Was Schaeffer's the previous run making this the 1st run with RLI?
What filters? Air filter interval?
Any fuel adds?
Spark plugs?

 

[TrailRunner]

This engine has NGK plugs with 10,000 miles on them. I think they are palladium plugs.
The air filter is a WIX, changed every 10,000 miles.
Run fuel injection cleaner pretty regularly, with regular gas.

It does 24-26MPG in the summer, but about 20-22MPG in the winter.

This is the 1st run with RLI. The RLI is cleaning the engine like AutoRX I hear. The next run is supposed to be better. I'll check in another 10,000 miles which will be 6 months from now.

Both of these oils appear to be great choices for your Honda engine. On your comparison please double check your numbers (fuel% looks reversed).

Nice report, TrailRunner. I expect your next RLI run/UOA will do even better, as the Schaeffer add-pack is cleaned off the engine internals and RLI's is deposited instead.

Buster, a TAN-TBN reversal of this magnitude would normally have caused much higher wear. RLI lasts longer after the reversal. Or, since RLI starts with a higher TAN as a consequence of its composition, it may thus not be directly comparable to 'regular' oil TAN readings.

Here's the UOA I posted some time ago. I did just the opposite, I switched from Biosyn to Shaeffer's. I'm curious, what's the first number you look at, TBN,TAN, Iron?
I'm told the iron spike with the Biosyn is a nonissue and related more to the cleaning than anything else.

Whatever's first on the report!

 

[TrailRunner]

The original fuel dilution number was incorrect. (I was planning on you not noticing my correction.)

I'm looking for a way to reduce fuel dilution. Has anyone tried a cold air intake on a Honda V6? Did it remedy this issue?

 

[UncleRunkle]

How new are your O2 sensors? maybe check those if fuel dilution is off.

 

[INDYMAC]

I have chased everything I can think of (and the experts on BITOG) to improve fuel combustion on two of my vehicles. I don't have a Honda V-6, but my 2000 Tundra V-8 came back with the best fuel dilution so far after changing all the O2 sensors and adding FP+ at 1 oz/10 gal to the gas. I'm starting to consider changing O2 sensors at regular intervals, even if there is no CEL or code for a malfunctioning sensor. For my wife's G35, I'm not sure it will help though. Her 3 mile drive to work will never allow the engine oil to warm up enough to come out of the rich fuel/air mixture assigned for cold engines. I'm afraid short OCI's are the norm on this one.
