[AITG]

Here's my UOA on the latest change alongside the last two changes. I added 1 qt. at 7200 miles after the change.
My OLM was down to 21% but I had a 3,000 mile trip coming up.

The first change was AmsOil, the last two Kendall. Based on these numbers, I'm happy with Kendall and using the OLM to set the drain.

Wow! I would be sticking with that stuff! PERIOD.

Thanks for the UOA.

 

[KCJeep]

Impressive!

Look typical for a Dmax. Keep doing what your doing

 

[Cory1337]

Impressive! What is the differ in cost per quart?

I saw it at a local Flyn J is was high 14.00 and some change per gallon

 

[AITG]

I bought it by the case for 12.50 a gallon about 18 months ago. I'm now out, so I can let you know case price once I go to the distributor next week.

Man, those DMaxes are easy on oil, aren't they? Based on the analysis, even at 21% the OLM is pretty conservative at 8.2K miles. Considering you got that oil for $12.50 a gallon, you really got a great value in it. Wow,
What is the driving situation for this truck? I always like to correlate a UOA to the driving situation.

 

[SteveSRT8]

Nice! Love those Dmax.

Sounds like Kendall has a great formula there.

The truck is used to pull a Boston Whaler: short trip, launch ramp idle time, boat and trailer weight about 4500 lbs. or haul a Lance 1121 camper. Gross weight with camper 12,400 lbs.

This change included a 3100 mile trip from MI to FL and return.

Occasionally, we just drive it because its such a nice ride.

It's really funny how that works.

I had an unscheduled trip to Illinois and my wife actually asked if we could take the Dmax! So we did.

Averaged 19 mpg too.
