This is a 2004 Honda Accord 2.4 engine 123,000 on car-14,900 on oil 7 months service. I added 1.5 quarts of oil (last added about 2000 miles before changing the oil) in the duration with a four ounce Auto RX maintenance dose, and put an ounce of lube control in every 1000 miles. I added a little less over this oil change interval than the last run with redline 5w20 with about 3000 more miles of oil service. I always keep the oil right at the tip. The first column in the previous run of redline 5w20 for 11,900 miles 7-8 months of service. The second column is the current run of redline 5w20 for 7 months with 14,900 miles of service. I do have an oilguard 10 filter and amsoil eao 13 filter. I have an amsoil air filter in engine. I changed the oil and replaced oilguard 10 system with slightly large 15 system. I also replaced the amsoil eao13 with amsoil eao 20 which is a larger filter but with similar threadings to fit 2004 accord-4cylinder. I used amsoil pi also a shall gas additive. I wonder if I over-additized with fuel stuff cause percentage of fuel seemed higher in second sample. I drive in rush hour traffic each morning 45 miles one way from york county pa to Baltimore MD area. I work in Baltimore city a couple nights a week and drive in city traffic then. I usually go home in non-rush hour traffic so have pretty clear sailing on drive home. I drive a bit aggressively and over speed limit, but usually with flow of traffic-unless have passive aggressive slow left lane driver who causes the most accidents.
1st Column 11,900 mi OCI (7-8 months) car had 107,000 miles total.
2nd Column 14,900 mi OCI (7 months) car had 122,000 miles total. Both samples are Redline 5w20-the second sample was more Redline 5w20 with SL bottle, 1st sample had more SM redline in it. I used auto rx four-five ounces on each. The first sampe also used lubeguard engine additive. The second sample used one ounce Lube Control Additive every 1000 miles. I put a few ounces in at 1000 miles then one ounce per 1000 for entire interval.
