Mobil 1 Truck & SUV 5W-30 / Shell Rotella - T / API CI-4 oils:umbrella:
Why do these HD Oils still have ZDDP ?
[...and why are these the ONLY Oils to run in your 'Quad Kamm'd Beasties' ?]
Because..........
Over the road Tractor Trailer 'Big Rig' Corporates would have been losing engines at an alarming rate - and the EPA knew this - knew of the headache it would cause American Commerce.
So the EPA excluded 'Delvac' > HD engine oils > - Diesel Engine Oil - from the Zinc ban.
thENnn........ 'Delvac' was renamed Truck & SUV Oil - since the weight classification of 'Heavy Trucks' included them. [ read for more SALES 'n so as to get around the EPA ]
The Trucking Lobby received quiet behind closed doors preferential treatment - or they were going to 'shut down' in protest of huge increases in down time / operating costs.

The Vanishing Zinc and Phosphorous
It is a fact than many SL oils now contain lower levels of ZDDP (the zinc/phosphorous extreme pressure additive) and that is a big concern to a lot of motorcyclists.
[*Note: because their owners don't want them turning to scrap slowly - or - quickly ]
ZDDP is a last resort protection against metal-to-metal contact.
[*Note: When the ZDDP ban became effective - many American Car manufacturers running lifter / pushrod engines began having high rates of failures. CRANE CAMS / COMP CAMS etc. began having 'Failures' - big crisis until they came up with a different hardening process ]
Whereas a few years ago the zinc level was typically 0.12% to 0.15% in SG automobile oils, some SL oils now have as little as 0.05%.
[*Note: Now some 8 years later - most have NO ZDDP ]
However, this in itself may not be a problem since normal operation of a motorcycle on the street would never result in metal-to-metal contact any more than it would in your automobile.:smlove2:

Heavy-Duty Oils
My favorite oils and the ones I most mostly recommend for HD use, are the "heavy-duty" oils.
They are commonly misunderstood, and often referred to as "diesel oils."
They are NOT energy conserving, have higher zinc levels, as high as 0.16%, and by virtue of their multi-duty have a better engine protection package than an oil that is only rated "SL".
These heavy-duty oils were rated SJ or SL, plus CH-4.
[*Note: The SJ or SL ratings NO LONGER carry ZDDP - and CH-4 is now API CI-4] ]:flowers1:
They are currently closer in formulation to the motorcycle specific oils and to the "SG" oils that many motorcycle makers recommend.
Following are some examples of these oils, generally 15w40 oils by industry convention.
There may be several other 15w40 oils that I am not familiar with.
1. Castrol RX Super 15w40
2. Chevron Delo 400 15w40
3. Mobil Delvac 1300 Super 15w40
4. Pennzoil Long-Life 15w40
5. Quaker State 4X4 Synthetic Blend 15w40
6. Shell Rotella-T 15w40 (my personal favorite)
7. SuperTech 2000 (WalMart) 15w40
8. Valvoline All Fleet 15w40
9. Castrol Syntec Blend Truck and 4X4 15w40

*Note: Most all of these are no longer HD engine oils as their packages have been removed entirely since *1999*.:crazy:

A fairly new player in the synthetic market is Shell with Rotella-T Full Synthetic 5w40.
It is not energy-conserving and according to Shell performs competitively with Mobil Delvac One full synthtetic, which means it offers even more protection than does Mobil One 15w50.
A number of motorcyclists have reported to me good results so far with his use of the new Synthetic Rotella-T.
Delvac One should be an excellent motorcycle oil but is generally available only at truck stops or in commercial quantities.
For those who may have connections with a long-haul trucking operation, where Delvac One is known to be used in oil change intervals up to 150,000 miles, or even more, you may want to try it if the price is right.

A synthetic oil formulated for gasoline engines may not meet the requirements for diesels.:684:
For example, regular Mobil 1 synthetic would not be a recommended oil for the Dmax.:crucified:
Mobil Delvac 1 5W-40 meets/exceeds the API specification for the Dmax.
(http://forum.thedieselpage.com/ubb/u...=007405#000000)
Mobil 1 Truck & SUV Formula is supposed to be relabeled Delvac 1, and is used by forum members.
Shell Rotella T is another synthetic that meets/exceeds the API CI-4 specification.

*Note: 'BMW OIL' - sold by BMW for their vehicles > cars and trucks and motorcycles < is MOBIL Delvac > bought by BMW from MOBIL and Relabled 'BMW OIL'.:yeah:
Delvac / Rotella T are the ONLY TWO engine oils to run in our Magnificent DOHC V-8 Engines.:squareeyed:
