was recently informed (at regular oil change) that no-oil showed on dip-stick
upon arrival (137.xxx). haven't noticed drips under car, or "blue-smoke"(burning
oil); always have regular Valvoline changes/maintenance...and eng. temp gauge did not show irregular level.
did have "ck eng light" about 1-yr ago/replaced cat convertor sensor & entire
catalytic-system, which was all original. Don't know what questions to
ask; or what to check-out with Honda tech.
At times, you may not have any visable "drips" or signs of leakage. Although, having NO OIL show on dipstick is a significant loss. You may need to simply keep an eye on the level. Make sure you wipe the dipstick off and replace for a complete accurate reading. They may have under filled, or the oil pan plug may have not been tightened all the way. Thre are many factors that may not be visable where you park. Again, keep an eye on your level check when you fill up your gas tank as a rule of thumb.
