The vehicle is our 1996 Prevost XL40' chassis Liberty motorhome. It has a 1995 DDEC3 12.7L 470 hp Detroit 60 series w/83,900 total miles since new when sample #3 was sent to OAI Aug.of 2018. We purchase the bus

We use the bus almost exclusively in the warmer months of the yr. We go from our central TX home to the mtns of CO occasionally. Mainly we use it to pull a 9k lb enclosed race trailer around the state of TX to go drag racing. The bus weighs 41k lbs wet, so combined we're @ 50k lbs. We rarely go faster than 65 mph. It gets about 7.5 mpg. The tranny is a 6sp Allison B500.
The only reason OAI has ever flagged something (see in report #1) was because I had a mix load in it, 80% Rotella T3 & 20% Amsoil AMO.
The Delo LE oil load in reports #2 & #3 was left in place until Oct of 2018. Runtime when changed to what's in it now was 38 mths with 9.5k miles. I did NOT take a sample. Why did I change the oil? Because DDC recommends it when the TBN drops to less than 1/3rd of the virgin #. Delo LE starts life with a TBN of 12. Mine was below 4 when I changed it.
In Oct of 2018 we installed 10 gal of Mobil Delvac 1300 Super 15w40, again the dual Fleetguard# LF9620 oil filters, but this time a Donaldson Blue air filter# 5065 with nanofiber technology. Why the switch to Mobil? In 2018 they had a mail-in rebate program, combined with a NAPA sale, I purchased 25 gal for $5/gal. Mobil is doing it again in 2019, but their not as generous. As of today this load/setup has 4500 miles on it. The next sample and report will probably be around Nov or 2020.
