Pennzoil High Mileage Motor Oil

This is one of Pennzoil's next generation high mileage engine oil. This is a conventional base stock engine oil with a special combination of unique conditioning agents and additives.
These additives are designed for vehicles with more than 75k miles. This oil is specifically developed to help stop and seal engine oil leaks as well as reduce oil consumption that is common with older high mileage engines.
Pennzoil High Mileage oil provides great engine protection while helping to dissolve and clean out the sludge buildup by keeping the contaminants in suspension until the next oil change.

This oil was a specific recommendation by the parts professional at my local store.

Switched at 170K to Pennzoil 5W-30 High Mileage...

1) Up until 168K I had been using Pennzoil or Castrol synthetics.
2) I just changed at Toyota:
- plugs
- coils
- plenum gasket
- valve cover gaskets
- front VVT solenoid
- coolant
NOTE: Pictures of front valve-train show differential heating/drain-back of oil. Right-hand side to left (towards timing gear) the color is "med-amber" to "brown," no sludge, but some "crusting"; above average in cleanliness, BUT what appears to be a design error in even oil flow.

First highway trip after work by Toyota dealer engine used 3qt of Castrol 5W-30syn in 700mi. Stuck ring?! (Note: most it ever burned was 0.5-1.2qt synthetic in 3,000-3,500mi; have owned the little truck since 48K)

Post atypical oil consumption:
3) Put in Castrol 10W-60 syn...NO oil loss on road trip of 900mi. ZERO loss.
4) Followed with 4:1 Pennzoil 5W-30 High Mileage + Marvelous Mystery Oil.
(rolled around town for 1 week to clean out engine --first time)
6) Changed oil to correct weight & filter
(Penn 5W-30 High Mileage + Toyota factory filter as usual)
7) Second road-trip to same destination, 900mi...ZERO oil consumption.

NOTE: Toyota mechanic and I know the engine design and sludge problems associated with this engine class. My oil change interval since purchasing has always been 2,500-3,500mi. plus I change the coolant per the recommended time/mileage. Main engine seals replaced at 90K with timing belt. (Did not replace valve guide seals.)
MY MECHANIC (former NASCAR Master Tech, now with Toyoda'r, recommended switching to conventional high-mileage oil to see it is would solve the recent consumption. Switching to Pennzoil appears to have done just that --no consumption.

CAUTION: I have been told that once you switch to high-mileage oils to never switch to non-high-mileage oils. Apparently the oil seals once they "swell" need the additives to maintain that state.

Heck...Pennzoil High Mileage seems to work and it is totally inexpensive!
The Toyota oil filters are good for 7,500mi. I think I will just drop the oil every 2,000-2,500 at the local outdoor place before changing the filter at the 5K mark.
I am off the extreme long life of keeping my precious Red Line ester-based OR Pennzoil Ultimate synthetic oil in the pan for some extend period (which for me was 4K/oil change).
---I am just going to do the OCD guy-thing and change my oil every 2,000 with this Pennzoil. Why not?!!

By 

from Chesterfield, VA, United States

Comments about Pennzoil 5W-30 High Mileage Conventional Motor Oil (1 Quart):

My son is a mechanic and does my oil changes roughly every 3000 miles. But with all the running I do it's usually more like 5000. I'm constantly on the go with everything from doctors appointments to softball practice. But no matter what when it's time for my oil change everything looks good. I wouldn't use anything else. My truck is my lifeline for my family.
