|Blind Dog||I think Amsoil is a good product. I used to sell it on the side for extra money until I didn't have time for that anymore. I would still sell it to a friend or use it myself.|

Quaker State Defy, 10W-30. 3000-5000 miles or 3-5 months. (this is a syn. blend with about 900 ppm "zinc" according to what I read.)
QS is a SOPUS (Shell) product same as Pennzoil.
The only thing Pennzoil has in common with the old Pennzoil is the yellow bottle since 2002, when Shell bought the name and reformulated it. I think it is one of the best out there now. I see a lot of bagging on PZ from people who cheerfully use Shell motor oils like Rotella, but it's the same company now.
Besides, a lot of old engines sludged regardless of what oil was used, and since Pennzoil was the one of most used oil brands, I strongly suspect that even the old Pennzoil got unfairly blamed for that most of the time.

|HRR1||Mobil1 0-40 full syn,change every10,000 miles, Mobil 1 filter. If not that Mobil1 5-20 extended performance still change at 10,000 miles. I read everything I could find on oil when I had two Miata's. Started with Amsoil-it is not without it's own issues and is generally more expensive than M1 and obviously harder to get. Like I said you can read about this stuff for hours including lab tests and engineering studies but the bottom line is full syn M1 and change at 10k. You can go to 13k or so with no harm but things do start to degrade at 10k ever so slightly. My Mercedes typically went 12 to 13k between a change was called for from the on board computer. I lived in Phoenix! Admittedly, the Mercedes held nine plus quarts of oil. Stop wasting your money on too frequent oil changes. BTW 10W-30 full syn is a meaningless number as it relates to DINO oil. It is also a poor choice. Go with one of the two I mentioned at the start. It is made up so the consumer thinks he knows what he is buying.|

|Noshow13||I'm running Pennzoil HM 10w30 right now, next change will be Quaker State Defy. I usually stick with Pennzoil or Quaker State in my Jeep & Silverado.|

|HK_Runner||Another good one is the Valvoline Durablend. Solid UOAs.|
|05-26-2012 11:25 AM|
|TJDave||Valvoline, cause I like their commercials.|

|HK_Runner||There are bad oils. They are always these small no-name brands (not the small exotics). There are several with such low viscosity that they can instantly harm your engine. Best to stick with the big names and the exotics (redline, Motul, Motorex, Total, etc)|

|teknoid||Penzoil 10w-30 and Purolator filter every 3-4K miles. I've used Penzoil for 37 years, and have never experienced any major engine failures. The highest mileage I've had before trading was ~285k. The wife's Monte has ~170k on the clock, and was bought new. It's never seen anything but Penzoil, and runs like a clock (Digital, since no ticking is involved). I doubt that it matters what oil you use, as long as it is changed regularly. Filters are a whole different story.|

Since the PO used synthetic, I've continued to use it. Mobil 1 10W-30 in summer and 5W-30 in winter. FWIW I use the Motorcraft (Ford) FL-1A filter.
I was changing oil and filter every 5K but I've extended my OCI to 8-10K. With 133K on the I-6, I still don't need to top it off between changes. I just checked the oil today and didn't need to add a drop at 6500 miles since the last change.

I'm using High Milage Vehicle Pennzoil 5W-30 Now as a test for Oil Consumption in my 07 Mexican 3.8L.... So far it's only used 1/2 quart in 620 miles on this change.
When I change, I may try a different brand until I see whats going to run with out dripping out of the tail pipe...
I hate looking in my rear view mirror and seeing the EXON VALDEZ bearing down on me.
Filter is Puralator .... "BH"

|theheilis||Shell Rotella 10w30 and a Wix filter every 3K.|
|05-23-2012 10:32 AM|
It looks the leaders are Other Major Oil brands, Full Synthetic and 4000-6000 miles change interval.
|05-23-2012 04:27 AM|
|MrSig||I've been using synthetic since new 5 W 30 I change it about 6,000-7,000 and I have 60,345 on her now. She runs great.|

Valvoline full Syn fluids in everything.. But I am biased based on the fact my wife works for Valvoline so I(she) get a killer discount at all of their oil change places in KY.
Prev to that I ran Amsoil.
Every 5k miles.
Valvoline or Wix filter, fram won't touch anything of mine.

Mobil super 5000 I get the oil change specials from pep boys 12.99 5 quarts and a filter. Or I get the 5 quart jug from wal mart
|05-22-2012 09:24 PM|
|BT||Penzoil with a Fram oil filter. I change it every 4 to 5 thousand miles. Which is usually every 6 months.|
|05-22-2012 08:59 PM|
Amsoil seems to be by far the best. With their filter its 15-25k depending on the car\driving conditions.

|HK_Runner||That is not true- not in the past 10-15 years anyway. Some engines (Chrysler's especially) were prone to sludge buildup if oil was not changed frequently. Pennzoil makes among the best oil out there. My old Honda Accord use Pennzoil regular and changed every 5,000 miles. The engine was shiny and I sold it at 159,000 miles. The next owner (my friend) took it to 220,000 miles before totalling the poor car. Had no issues, excellent gas mileage, and if you looked down the engine oil fill area, the components were still shiny and the dipstick was aso shiny. I have also used the other oils with similar results but some engines are prone to sludge buildup. It had become much better recently.|
