Re: Oil pressure dropping on right turns
My A does exactly the same thing. When cold, the low pressure lasts MUCH longer than when the engine is hot. My theory is that the pump is filling the valve chamber and the thicker oil (15W-40) takes longer to run through the overflow tube and back to the pan so the effective level at the pump is lower. When the engine is hot, it lasts only a few seconds. When cold, it can last a minute or so after a significant turn. I TRY to let the engine warm a bit before driving off... or take it VERY easy on right turns until it's warmed.
