Given the following information -
- engine consumes/burns 16 oz of lube in 2k miles
- OCI is 66.7% used; 1k miles yet to go
- unknown location of the operational area (Alaska? Death Valley?)
- desired volume to add is 1/2 qrt
Knowing the penchant for BITOGers to debate the nuances of the...
As for the OP's UOA in this thread, there's minimal value in this data. One can reasonably conclude the following:
- the engine has no internal coolant leak
- we cannot assess air-intake leaks because the Si (attributed to silicone sealers) has not settled; so one cannot discern it from silica...
You didn't mention how old it was.
My Gravely (probably 25 years old or more) had the same issue. There are three little cube-style relays. I replaced them all (they are identical part numbers) and haven't had an issue since. This is a common thing with older units; the relays won't stay...
Meehhh ...
So it's a tad thinner on the top end. I've never considered it a "must-have" to thin out my diff fluid in order to gain micro-fractional mpg improvements. For Joe Average consumer, this won't have much appeal. For someone who manages a massive fleet of vehicles, it might make...
The transmission service done was to the hydraulic portion of the system.
The issue you describe is likely due to an electrical issue; some "permissive" criteria not met such that the electronic controls are not allowing the shift interlock to open.
To me, those sound coincidental.
So, you're going to buy TT gas and then put in additive on top of it? That seems wasteful. And many of the PEA additive products specifically state to NOT use it all the time.
Or, are you going to use "standard" (non-TT) gas and then put in additive? This seems dubious to me, because you're...
The right "plan" is to use the UOA data and decide what you OCI should be.
So this thread is premature; it's just conjecture until the info comes back from the lab.
No.
I meant to imply that we'd like to know what brand/model/engine you're addressing here. You have yet to identify the "application"; what car/truck are these photos from?
