Replying to: dagwood2 (May 04, 2009 5:17 pm) The Dark Oil Myth Are oil changes every 3,000 miles really needed? I use dead dino in my minivan and have pushed the usual recommended 7,500 interval out to 11,000 miles at least once. It's a '99 and ~133,000 miles on it. Oil's a lot better than it used to be. If you really want to know what shape your oil is in, pay the $20 for an analysis. |

My wife and I purchased a new 2007 Honda CR-V in late 2007 (November). The vehicle had 45 miles on it when we drove it off the lot. As with any new vehicle (and being old school), we were careful to drive it easy for the first few thousand miles to ensure proper break-in. The vehicle currently has less than 10K miles, and I do my own oil service every 3K using Castrol 5-20W (recommended viscosity), and new Honda filter. After the vehicle had approxinmately 5K miles on it, we took a trip from Central California to Los Angles and back (approx. 700 miles RT). Upon our return, I noticed that the oil level was down nearly 1/2 quart on the stick. After another regular oil change followed by another 500-mile trip, I found the oil to be a bit low on the stick again. Honda recommends using 5-20W oil. However, living in a more moderate climate (Central California), I can't help to wonder if the 5-20W viscosity isn't too thin for our conditions! I wrote a letter to Honda expressingf my concerns and they resopnded that I need to continue using the 5-20W, and add oil if needed. Am I over reacting here, or has anyone else had this experience? Does anyone use a heavier (5-30W) viscosity?

Replying to: trcm (May 05, 2009 2:25 pm) You'll need a longer test to test oil consumption. You might have the dealer check your PCV valve, and also complain about oil consumption. Maybe there's a leak you can't see. At least the complaint will be recorded. Generally, there's no cause for alarm here unless you continue testing and find that the oil consumption in miles per quart is slowly increasing as the miles pile up. An engine can use some oil and run forever, but when it drops to say one quart per 1000 miles, that really gets my attention, especially on a newer vehicle. Next oil change, try to measure it very accurately. And make sure the dealer makes note of this on the repair order....and check the PCV system. |

Replying to: sailorboy1 (May 04, 2009 2:46 pm) But they don't. Some people drive mostly on freeways and at moderate speeds and live in an area with a mild climate. For them, a longer interval between oil changes makes sense. Honda's system attempts to account for these differences. It makes sense to me. |
