I was reading the thread on cam wear and diesels, and it reminded me that the only real weak point of all the early four cam Ferrari engines was early camshaft lobe wear. ( I just checked mine and they're OK but show some "eggshelling" at 6K miles since regrind.) So maybe I should go with an HDEO oil that's specifically designed to prevent this, as the other aspects of these oils are excellent also.
At the Mobil website it says Delvac 1 5W40 meets ACEA E5 specs. What's that? There's no mention of B.
The Rotella T 5W40 is listed as meeting API CH-4, CG-4, CF-4, and CF. No mention of other specs. Does that mean it's not as good as the Delvac 1?
And here's a possible scoop: On Mobil's site they also list Mobil 1 Truck and SUV oil. Here's the technical info:
Mobil 1 Truck & SUV is a 5W-40 viscosity grade product and is recommended by ExxonMobil where 5W-30, 10W-30 and 15W-40 lubricants are specified. Consult your owner's manual for specific manufacturer recommendations which may be required for warranty protection.
Mobil 1 Truck and SUV is recommended for use in gasoline and diesel powered trucks and SUVs built by Ford, GM, and DaimlerChrysler.
Mobil 1 Truck and SUV further meets the diesel engine requirements of Cummins, Powerstoke, Duramax and Navistar – for bigger, heavier duty truck applications, such as delivery vans and utility fleets.
Mobil 1 Truck and SUV is fully compatible with conventional engine oils.
Specifications & Approvals
Mobil 1 Truck & SUV meets or exceeds the following industry specifications:
API gasoline engine standards SL,SJ
API diesel engine standards CI-4, CH-4, CG-4, CF-4, CF
Typical Properties
Mobil 1 Truck & SUV
SAE Grade 5W-40
Viscosity, ASTM D 445
cSt @ 40ºC 102
cSt @ 100ºC 14.8
Viscosity Index, ASTM D 2270 151
Sulfated Ash, wt%, ASTM D 874 1.35
Total Base #, mg KOH/g, ASTM D 2896 12
Pour Point, ºC, ASTM D 97 -45
Flash Point, ºC, ASTM D 92 226
Density @ 15ºC kg/l, ASTM D 4052 0.854
These numbers are EXACTLY the same as those listed for Delvac 1. So the same oil in a different bottle for mass marketing? Would be an excellent business move!!
And for those who are interested, there are few choices for oil filters for a Ferrari. Back in the 70's the cars came with Frams, but as you know the company was bought out or whatever and now they make garbage. So we all started using UFI's which I think is OEM now. But then there was a problem with them blowing out their seals on startup, so you suddenly had 8 quarts of oil on your garage floor. Most people switched to Baldwin filters at that time. UFI has probably fixed that problem by now, but a lot of people still use Baldwins because they seem at least as well made and are usually cheaper. I bought a bunch of Baldwins back then and am still using my stock.
