Rated 5 out of 5 by Hemi300C Good oil I recommend
Started using Pennzoil HiMi in my personal car and the difference was nearly instantaneous although Hemis are know to tick even when brand new this oil softened the tick and oil pressure ran much more in a range I liked. Being a mechanic and a auto repair shop owner that went from offering Valvoline to Pennzoil customers also notice the difference in their cars. Working on high end cars knowing their picky "oil choices" Pennzoil really works also if you own a Hemi V8 manufactured up to 2010 (example: 2000-2010) Do not use full synthetic ive seen plenty of Hemis come to an end early in life running synthetic I highly recommend Pennzoil Conventional and Conventional High Milage and all of Pennzoil motor oils

Rated 5 out of 5 by yankee pete great oil and the best
i switched to pennzoil high mileage when you first came out with it several years ago,i have a 2002 chevy impala that has 207,000 miles and uses none between oil changes and always use your high mileage 5w30 for my car,nothing beats pennzoil for the best performance and and protection for my car i definetly recommend it for everyone with a vehicle with high mileage

Rated 4 out of 5 by Texitalian i trust Pennzoil over almost anything I can think of. I just do not understand advertising the 20 weight oil for autos over 75,000 miles. With that much engine wear, I want something with a t least a 30 weight. I am not talking 10 W 30 either.

Rated 3 out of 5 by David RX300 '99 LEXUS RX300 - 174K
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:
- plenum gasket
- valve cover gaskets
- front VVT solenoid
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?!!
