Really? So I don't have to change my oil every 3k miles? Cuz I think I was coming up soon for an oil change.[&:]

Nope. Heck for a couple of year FORD was like 5K Oil Change and Rotate for severe duty if they had one. Now they are edging up to 7500 as the recommended OCI. By an overwhelming number of Used Oil Analysis the SM rated conventional/semi-synthetic will go 5K without issue. Not much further in a lot of cars but will go 5K no problems at all. I like this interval. It is good number to go with tire rotations. 7500 is a bit to far in too many circumstances but 5000 seems to almost always be just fine. Jump to synthetic and 10K with none of the varnish build up of conventional and the same wear number rates.

So Yeah extending the drain interval with proper fluids and filter is not that big a deal. I would highly recommend getting the Amsoil EaO filter as it can reduce particulate matter in the oil over 90% over conventional filters.

Ok so from reading everything, I can run the same filter and oil for 10K without any problems? I live in Mississippi where the weather is ridiculusly hot 95-100 heat indexes. thats why I chose the higher weight, i was told the higher weight will stand up to heat more. I just want to be sure before I commit to the plan.

Use a better filter like Mobil 1, Wix, K&N, or Amsoil(My favorite by far, heck use this even if you use DINO). Then NO PRoblems going 10K

Some have had trouble with this oil. Might settle in like Redline will after a couple of oil changes but not sure on that yet. It is OK and so of the real oil gurus say it is OK.


Pennzoil Platinum, Mobil1 (not extended performance) or Amsoil would be my favorite choices(unless racing then REDLINE OIL). Although most synthetics will do 10K without much fuss.

Use 5W-30 or 10W-30 down in the south with confidence. Supposedly 10W-30 will hold up better (lower NOACK evaprotive) but could be prone to more start up wear even in the summer as it would stay out of operating grade longer. I used 10W-30 in the dead of a Chicago winter and got fantastic results so quit parsing it down to the 1/3 a gram of metal you'll save in 100,000 miles. Not worth it. I have 5w-30 Amsoil in now and after 4.5K on this Oil Change it is still on the top line with NO oil loss. YEAH!!!

Penzoil I found in colaberation with dura lube and a k&n filter are great I also run 5w 30

Skip the Dura-Lube and go with just oil.

FTC took a whole bunch of them to court and only lost to ZMAX.

Outside temperature. Breaking it down to its very simplest as far as the two oil weights max/min as far as temperature goes...the 10w-30 is for sub-zero, the 5w-30 is for 100+. Theres other factors obviously, but Chrysler recommends the 5w-30 unless your in an area that experiences sub-zero temperatures.

UHHHH..... NO! NO! NO!

0W-XX oil are rated at -35F
5W-XX oils are rated at -30F
10W-XX oils are rated at -25F
15W-XX oils are rated at -20F

The XX portion be it 20, 30, 40, or 50 are rated at 212F. Approximately operating temperature.

So the 5W-30 oil will protect the engine down to lower temperatures than a 10W-30. A 5W-30 will also be closer to operating viscosity at 70F than a 10W-30 thus providing generally better start-up protection than 10W-30 oil even in MIAMI, FL (for those who live in Ohio). Some older cars used to recommend (some new with old engine designs still do) 10W-30 in summer due to the lower Noack Volatility numbers and thus lower propensity for thermal breakdown and thus a more stable oil.

Synthetics with a decent oil filter such as K&N, Mobil1, Wix, or Amsoil EaO series have been shown to go 10K without any difficulty and keep wear number at or below 3K changes with synthetics and still leave less oil carbon deposits or varnish behind. So 15K can be pushing it but with proper monitoring and depending on driving styles and usage could be perfectly acceptable.

Spend some time over in the BITOG and look at the results of many oil changes and extended length Synthetics and you can see for yourself. But basically almost all cars in decent order can go 5K on modern Dino and 10K on modern synthetics and suffer no ill will or damage in any way. That is just how long it will last. To go longer you'd need to look into Amsoil and their EaO filters for optimum performance. I personally switched to Amsoil and am running a 6.5K interval on initial switch over and then will be on to 10K OCI. I have the extra protection of the Amsoil and EaO microglass filter. Right now I am at 4.3K and it looks like Dino at 1K. It is awesome.

Don't worry so much about color. Not a big indicator for the most part.
very informative post... thank you

I use nothing but mobil one on all my cars and change at 3000 no matter what it says on the bottle.
