8v71 oil filter and....

[Paladin]

Ok, three or four questions here:

I don't have the monstrosity here to play with and look at and I'm having a hard time finding the info.

What is the proper oil filter for an 8v71n?

Would Napa carry it?

Also, is there any difference besides maybe personal preference between Delo 100 and Rotella?

Last question, is the requirement for an oil change a function of mileage or time or both? If you have very few miles on the oil can you hold off or should you still change the oil yearly or whatever?

If it's a spin on filter it's Napa part #1970
Differences in oil:
  DD Publication 7SE270
          http://www.detroitdiesel.com/support/on-highway/manuals/Lubricants_Fuels_Coolants/index.asp
  API Classification CF-2

Oil change is a function of time, hours run, and engine condition, among other things. Have an oil analysis done and keep a history of the analysis findings.
This will tell you the condition of the oil and the condition of the engine.
One analysis test isn't really enough to be statistically meaningful. In the mean time, if you aren't putting a lot of miles on the coach, change once a year.

*These are only opinions, mine. Others may have different opinions, which is fine. Whatever works for you is good.

Dax -

DDA's requirement for the two stroke oil says a maximum 1% sulfated ash content.

Last time I looked at the spec sheets for Shell's Rotella, it was right at the 1%, while Chevron's Delo 100 was at 0.76%.

FWIW & HTH. . .

Dax, it seems that everyone has their own ideas as to what the oil change interval should be for a 2 stroke.
And since there aren't that many, if any, under the hoods of trucks anymore you won't get much input from that area.

For all the years I was shipmates with these screamin' demons on boats we changed oil about every hundred hours of running time (probably about 1500 miles) which looking back in retrospect was probably too often..and a waste of good oil.

By contrast, now, I only run my bus about the same amount of milage (annually) and since I'm the one paying the freight I've decided to extend the interval to 3000 miles and then take a look at it then or take an oil sample and go by the results to make a decision.  If I were logging 5K a year...I believe I'd change oil once a year and let it go at that.

It's my opinion that way too much good oil is disposed of too early.

Trying to find Delo 100 40# out here in the west is next to impossible so I have went to Rotella 40#.

Not if you use the Chevron Lubricants "Where to Buy" locater (http://www.chevron.com/products/prodserv/nafl/wheretobuy.shtm).  Plastic money and UPS can have a couple of cases headed to Quartzsite from Phoenix, Las Vegas or Indio for delivery within a couple of days or so.

Just have to plan ahead a little.

Same goes for other folk in other parts of the US & Canada - the locator's a great tool if you use it.

Russ...thanks a ton for the Chevron Locator...big help

Here is a good site that explains the Ash content and where to purchase the oil.  The guys at O'Reilly's said they couldn't get it.  I gave the codes on this site and low and behold found 9 cases in Atlanta, 2 are headed my way.
You have to purchase it by the case, that's 6 gallons at $9.49 per gallon.
Hope that helps!

Went to Chevron Locator. Two of the suppliers  for AZ said don't have it any more waiting for answers from others. Two email address no good anymore go figure.
