I've had an issue with intermittent long cranks/hard starts. When the car eventually starts the RPMs are lower than they should be until I press on the gas a bit.
Recently, I've changed my engine oil to 5w30 Castrol Extended Performance and the hard starts went away.
My previous oil was 5w30 Dexos 1 Gen 2 Castrol Edge Black Bottle API SP rated (also ACEA A5/B5 rated) , it's been in the engine around 11 months and had less than 7k miles on it. There were around 5.5 quarts when I drained the oil out, so it wasn't too low.
Why would the old oil cause long cranks, hard starts, and low RPMs on startup? Had anyone else experienced something like this?
