05 Honda Civic DX, 4 speed automatic with 1.7L 4-cylinder SOHC engine
Date of oil change: 01 Nov 2007
Oil usage: 09 Aug 2007 – 01 Nov 2007, 12 weeks, 416.67 miles/week
RLI 0w20 BioSYN, 3.4 qts (RLI oil batch #1048-061807)
Dyson Analysis
Oil: 5,000 miles
Makeup oil: 0
Car: 40,872 miles
NOTE: sample pulled for UOA, oil not changed
Oil Filter: Honda/Filtech OEM 15400-PLM-A01 (new filter in place this OCI)
Air Filter: Fram CA8911 (new filter in place this OCI)
Oil/Fuel Additives: n/a
Gasoline used: 10 fill-ups with Shell brand 85 octane (same station, same pump each fillup)
Honda recommends 5w20 oil at 10k miles or 1 year for normal driving, and 5k miles or 6 months for severe driving for my 1.7L 4-cylinder engine. My commute is primarily highway, 72 mile round trip with minimal traffic. Documented MPG:
0-10K OCI 41.41MPG (Aug05-Feb06) UOA
10-20K OCI 44.13MPG (Feb06-Sep06) UOA
20-30K OCI 42.19MPG (Sep06-Apr07) UOA
30-35K OCI 42.51MPG (Apr07-Jul07) UOA
35-36K OCI 43.76MPG (Jul07-Aug07) oil not tested
36-41K OCI 41.82MPG (Aug07-Nov07) *avg MPG is down, but I drove 10-15MPH faster this OCI.
Car was driven ~70 miles highway prior to oil change (representative of my daily commute); car cooled only long enough round up my sampling equipment; sample pulled via vacuum pump.
I tried to make this as much of an A/B comparison as possible to the previously tested Havoline 5k OCI. The only variable this OCI is the use of RLI 0w20 BioSYN (same commute, same Shell gasoline, no oil/fuel additives, a fresh OEM Filtech oil filter and a fresh FRAM air filter in use).
