Oil Type? Winter Coming up

I always run 10w30 synth (but regular would be fine) in wintertime on a
high mileage engine.

I am using 20W50 year 'round in my 270,000 mile 1988 Cabbie, even though I
have new mains and rod bearings and a new oil pump. After warm-up, oil
pressure reads 1 bar at idle and 2.5 bar at 2000 RPM. The engine is a 1.8
liter 8 valve gasoline with automatic transmission.

I use 10w40 all year for my 1986 Jetta. VW dealer says they use 15w40
diesel for all cars all year around.

Obviously depends where you live! Alaska has different winter demands
than Florida.

Here's what Bentley recommends for a gasser of your vintage:
5W20 or 5W30: -20F to +20F
10W30: 0F to +60F
15W40 or 15W50: +10F to +90F
20W40 or 20W50: +20F to +90F

Personally wouldnd use a single-grade oil, except where needed: SAE40
for +70 - +100F.

BTW, oil pressure values can be very misleading. It's primarily a
function of the resistance that the oil is seeing going thru the
passages. Thus, 20W50 (at a given temperature) would show much higher
pressure than 5W30 but doesn't necessary give any better lubrication.

At least it makes that oil buzzer stop.
