Hi,

yesterday 'cause I have to go through inspection I changed plugs, pcv,
and oxygen sensor, and added a quart of oil... 10w-40 (usually calls for
10w-30)... drove it out to mom's... fine... on the way home the
"service" light comes on... all the connections seem good and it seems
to run fine... is this just the result of the 10w-40 bumping up the oil
pressure a bit and I should just change back to 10w-30 immediately? or
more serious?
