Preventative Maintenance. No leaks, sludge, or oil consumption. My Venza has a 2GR-FE V6 is not known for oil consumption but cleaning up the piston oil control rings up for the next 120k.
Note: The Toyota dealer just replaced the scheduled: iridium sparks, orig serpentine belt, pink coolant...
Your observation is correct. I saw a HPL passenger engine oil voa and the oxidation is around 20.
The interesting thing is that the recommendation of 20% by volume of EC to engine oil has an equivalent oxidation 1 to 5 ratio (oxidation is in absolute/cm 20 vs 113)
In other words, (20*5 qts +...
Gotcha, thank u again.
I am re-posting the EC uoa. The oxidation is high and is expected for a cleaner. Typically, the oxidation baseline is around 20s for non-neglected uoa or a voa.
HPL EC voa
When u say HPL, u mean HPL EC? Am I correct?
I just bought 6 qts of HPL EC. I think Dave’s comment 30-90 days is conservative and errors on the side of caution.
Thanks, I will probably do less than 60 days to be on the conservative side and not to damage seals.
In ur situation, did it help clean or loosen things up?
My Toyota V6 @120K does not consume oil and has been getting a 5K OC and a XG9972 Fram Ultra @10K. I am interested in preventative maintenance on the piston oil control rings. I asked Dave the following:
Response:
If it takes 30 -60 days to go 5000 miles - i would go the full interval.
If...
When I do the buy 2 and get 1 free and subscribe for a 6 month interval, what happens at the next shipment? Do I automatically get another buy 2 and get 1 free deal or does the subscription goes to qty 2 5qt jugs?
