Had my Silverado oil changed at local Chevy dealer a few days ago.
While under the hood replacing the airfilter yesterday I noticed that my dipstick was showing an oil level as seen in the photo.
An email reply from the serv. dept. gave me the proper instructions for checking the oil level,
"WHEN VEHICLE HAS SAT FOR 2 HOURS YOU HAVE TO START THE ENGINE AND LET RUN
FOR 10-15 SECONDS, THEN TURN OFF AND WAIT 5-10 SECONDS. REMOVE DIP STICK,
THEN REINSERT AND PULL AND READ OIL LEVEL. THIS IS THE PROPER PROCEDURE.
WHEN VEHICLE SITS FOR 2 HOURS OIL DRAINS FROM THE TOP OF THE ENGINE TO THE
OIL PAN CAUSING AN OVERFULL READING. Thanks Tim M."
Service bill shows they put in 6 Qts of oil into my 4.5 Qt. engine!
(my fault for not checking the print-out)
This is what 6 Qts looks like in a 4.5 Qt oil pan.
Pd $51 for this official Chevy Serv. Dept. oil change.
Headed back for a chat with Tim.
