2008 BMW 135i Coupe: Plus One Quart of 5W30 Synthetic

August 11, 2009


Last night during a 25-mile drive home from the San Gabriel Valley, our long-term 2008 BMW 135i coupe began showing its standard "!" within a triangle alert within the trip computer display. I'd seen this alert before when the car was low on fuel, but that wasn't the case this time. So when I arrived home, I ran an electronic check of the oil using the car's fussy control stalk for the trip computer.

Within 30 seconds, the car told me it was thirsty for a quart of oil. (Note: I didn't get a picture of the display at the time; this photo was taken this morning after the 3-mile drive to the auto parts store. And that is why the engine isn't fully warmed up here. Please do not worry. Everything is fine.)

Page 117 (or is it 118?) of the manual says full synthetic 5W40 or 5W30 is approved for the 1 Series. I put in 5W30 Castrol Syntec, because that's what Kragen had. Spillage was zero thanks to my yellow funnel.
