Yes. Here is some data and follow the discussion: 10/2007: This is my neighbors 2003 Ferrari Enzo with a total of 8,800 miles on the left column and my 2003 Enzo with a total of 3,000 miles on the right column (middle column as of today-2009). Both cars had 1,400 miles on the oil. His obviously had more break-in time. He had the oil changed by the Ferrari dealer using the required 10W60 Shell Helix Ultra Racing oil. I ran 0W30 Castrol GC. The recommended interval is 5,000 miles, less if on the track. This is strictly off track use in town and on the highway, probably 50-50 for his car and 90 percent city for me. His oil was tested by: http://www.youroil.net, while I got the full, total evaluation from Terry Dyson at http://www.dysonanalysis.com. 7/2009: Another 1,400 miles on the Enzo now with 4,400 miles, still not broken in fully. When I took out the GC I put in 0W-30 RLI. This is what we are testing here today. Again, tested by Dyson. Remember that his testing counts larger particles as well as all the smaller ones so other labs may give false lower values. My driving has been exclusively in town and most often back and forth from Home Depot for small items. Just before this sample was taken we drove to the Ferrari dealership in Tampa to test drive the new Ferrari California. Going there and back took a total of 2.5 hours or so and about half of the way back it rained (very hard). So the fuel dilution was probably much higher before this short trip. At no time has the oil temperature in this engine gotten above 180 F. This oil has been in for nearly two years but Terry Dyson says I should just keep going (and going and going). What is particularly interesting is that I put in 0W-30 RLI and the viscosity (with probably even a lesser dilution after this trip) is in the 20 grade area now. Remember that a 60 grade oil is speced. ................................................................................................................ _____________Shell..GC...RLI Iron___________ 32...11...7 Chromium ______<1...0....1 Nickel ___ _______ 2...1....0 Aluminum ______ 11...3....2 lead ___________ 16...0....3 Copper _________25...8....4 Tin ____________<1...0....0 Silver _________<.1....0....0 Titanium _______<1....0....0 Silicon __________ 7...3....4 Boron __________ 1...3....16 Sodium _________ 8...3....10 Potassium ______<10...0....0 Molybdenum ____ <5....1....2 Phosphorus ___1026..935...1032 Zinc ________ 1135..1228..1055 Calcium _____ 1454..1671..2108 Barium _______ <10....0....2 Magnesium ___1219...526..53 Antimony _____<30...0....265 Vanadium ______<1...0....0 Fuel %Vol _____<1...1.2...1.3 Flash_______not done..335..320 Abs Oxid ______ 34...10...127 Abs Nitr _______ 11...8....8 Wtr %vol ______<0.1...KF=247....KF=1063 a little damp, but not bad Vis CS 100C __ 15.8...11.8...8.6 Vic CS 40C___not done...66...44 SAE Grade _____40....30....20 Gly test ______NEG...0.37 not antifreeze....0 TBN _________not done...7.9....5.9 Visc Index_____not done..154...177 Soot__________not done...0...0.01 http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=1543003#Post1543003 aehaas
