BOB and MARCO- Smarty High idle

Tuning Platform of Choice

Delo for me

635,000 miles on a 94 ctd

325,238 miles on a 92 ctd

170,000 miles on a 97 ctd



all these trucks are driven daily with power mods & the 94 & 97 are pull trucks that see GCW over 25,000 every day.
 
Mobil Delvac 1300 Super 15w-40 here! Wal-Mart's price is $5. 88 per gallon. Good price and no stink as far as I can tell. :cool: I change every 4000 miles and use Stratapore filters from Geno's. :D
 
Oil

Rotella from Wal-Mart and Fleetgard filters from Cummins dealer.



On 3000 miles change intervals too. Wouldn't want that drainplug to seize in the pan from not taking it out often enough. ;)
 
If this were the Ford or VW site, Mobil Devac 1 would be on the first line. Why doesn't anyone with CTDs use one of the most proven and few fully synthetics on the market? Most of your list is either dino or just severely hydrotreated group IV base stock.



I use Delvac 1 in everything gas and diesel year round. I work for an oil company (upstream) and used to do lube blend design for a small lube manufacturer and was chief technical resource for regional destributor of two other large competitors to Mobil/Exxon. I drive the only PSD in our fleet, and change at 10k with a Baldwin bypass filter, towing heavy most of the time.
 
I changed oil and filter at 1250 miles using Rotella T 15w40 and Fleetguard Stratapore filter. I will continue to use Rotella T 15W40 and Fleetguard/Mopar filters and use a change interval of 3750 miles. My truck is a daily driver and does limited light hauling of less than 1K lbs. It is alway parked in a heated garage year round and when driven it is ususally for at least a 20 mile distance in the 50-70 mph range. If I lived in the extreme temp areas of the USA or my truck set outside in "0" degree weather I would consider synthetic oil.
 
Amsoil

The original owner used Amsoil after the first oil change. I'm continuning with the same products!!!!!
 
OK OK!!!!!! I can't take this anymore. I can't keep this valuable confidential information from you guys. The BEST and MOST highly prized oil and additive package is not just the John Deere 15W-40 Plus 50. I spoon in 7 pints of "Homer's Duck Butter" with each oil and filter change. It meets and exceeds :



* API Engine Service CF, CF-2, CG-4, CH-4, CI-4, SH, SJ

* MIL-PRF-2104G, MIL-L-21260D* (*Rust Protection and Acid Neutralization Test)

* Allison C-3, C-4

* Mack EO-L, EO-L+, EO-M, E)-M+

* M. A. N. 271

* Mercedes-Benz AG 227. 1, 228. 1, 228. 3

* Scania Long Drain

* Volvo VDS, VDS-2

* VW 505. 00

* Cummins CES 20071, 20072, 20076

* MTU

* EMA LRG1



and Homer himself personally checks to ensure ISO 9002 specs. are complied with as well as meeting his HPI, MIL-L-2104G-H, MIL-L-21260D-H specs. In fact, Cummins does not advertise this but they even spoon in 7 pints of "Homer's Duck Butter" at the factory as a protective break-in additive package for all of their production engines. Banks Engineering even used it in the Dodge Dakota for the world land speed record attempt.



Wow!!!!!! I feel a whole bunch better now! I just couldn't take keeping the inside information from you guys. Now the rest of you can enjoy the same benefits I do... ..... easier starts, 37 mpg, smoother running engine, faster oil pressure rise on cold start, smoother ride, ... ... ... the radio even sounds better! All this for $39. 95 a pint. Call 1-888-BR-549HO

;) :rolleyes:
 
Boy, am I confused. I read one of illflem's posts about the vacuum cleaner hose inserted into the oil filler tube so you could change the drain plug without loosing the oil. It took three tries before I turned the vacuum on, but then it did work. Oo.



Since then, I have been changing my drain plug every 4000 miles, without loosing a drop of oil. Are you supposed to change the oil also? :eek:



If we are to change the oil, I need more info from rfrazier on the "Homer's Duck Butter". :confused:



I do not like the snake oil products :( , so mean while I will continue to use the Delo :) , but I am willing to consider the duck oil. ;)

Wayne, sorry I forgot to mention turning on the vac in my instructions. If you want to drain your oil faster put the vac on blow.



rfrazier, alright another Homer's fan!



I use Homer's oil dye. It comes in six colors, one for each oil sump - trans, engine, differentials, etc. Makes it child's play to tell which oil level to check by the color of the puddle on the garage floor.

You might have something here that the Ford and Chevy guys might really want to buy. Think how much time this will save them??? You will need to expand the color chart that comes with the directions. letting them know for example what 2 systems might be leaking when 2 colors run together on the ground to form a new color. Example, I'm a Phord power puke owner and I have yellow dye in my engine and blue dye in my transmission. I come out of my trailer and find a puddle of green liquid under my truck. The chart would tell them that when your yellow engine oil leaks and mixes with your leaky blue transmission fluid it makes a green colored liquid. illflem I think you are going to become a hero to all Ford and Chevy owners :)
