Just looking at the history of a Perkins Diesel Engine that runs a Power generator on a farm 17 hours a day. Here are the last 8 analisis covering a total of 3744 hours. Engine now has 10,185 hours. The first 3 are Group I of an older CH-4 formulation, then 2 with the new Group I CI-4 formulation with Moly and Boron, and finally three with Delo. All are 15w-40, ambient temperature 25 to 38 C, High humidity and high dust.
Hours: 411, 401, 430, 380, 408, 431, 484, 406
Iron: 8, 0, 14, 9, 9, 8, 9, 7
Chrom: 0, 1, 1, 1, 1, 1, 0, 0
Lead: 7, 7, 5, 3, 1, 2, 4, 3
Copper: 1, 1, 3, 1, 1, 1, 1, 0
Tin - all zeros
Aluminum: 1, 2, 2, 2, 2, 1, 2, 1
Nickel - all zeros
Silver - all zeros
Silicon: 4, 1, 5, 3, 5, 3, 4, 2
Boron: 37, 20, 61, 97, 101, 20, 2, 1
Sodium: 4, 1, 5, 3, 3, 4, 0, 0
Magnesium: 701, 416, 1173, 307, 198, 60, 20, 14
Calcium: 1262, 1659, 1344, 2186, 2404, 2323, 3153, 3283
Barium - all zeros
Phos: 1066, 1045, 1096, 1203, 1079, 1288, 1182, 1276
Zinc: 1469, 1263, 1344, 1261, 1252, 1418, 1299, 1391
Moly: 3, 3, 2, 82, 104, 18, 3, 1
Fuel - all zero
Water - all zero
Visc 100: 17.97, 17.30, 16.11, 15.26, 13.88, 12.98, 12.82
Soot: 0.1, 0.4, 0.2, 0.3, 0.2, TBN: 7.0, 4.8, 8.0, 6.1, 6.4, 6.6, 8.5, 10.0
It's interesting to note that when they started with the moly formulation, only 80% of it showed up on the first analisis, then when they went off moly 20% carried into the Delo. BTW, the earliest formulation was running a 15.9 to 16.25 visc as virgin oil.
 
Thats a pretty amazing tabulation. If I convert that 10,000 plus hours into something like 1 hour equals 50 miles in a vehicle this Perkins has over 500,000 miles and very low wear rates.
What type of air filter does this Perkins use?
 
Hi,

Perkins - great motors

Steady state diesels seem to last forever
I have seen Isuzu diesels on ThermKing reefer units that have gone out to 25000hrs on mineral oils
I have done annual oil changes on these I've owned - about 2300hrs most have a FF and a bypass filter

Regards
 
Doug,
did you watch "Coltrain's Planes and Automibiles" ?

That was an awesome BBC/ABC series.

The perkins areticle was pretty good.
