I grew up on 10-30 or 20-40. This is SoCal. No freezing, lots of heat.
Synth oil is nice, but expensive. The concept of 0-20 oil, although
the manufacturer suggests/demands it, is just alien. We never freeze,
we just have to worry about the oil thinning out when the ambient is
I assume I'm worrying needlessly now, but I'd like to know why.

sorry but its strictly to meet gas milage specs. I wont use 0 anything
unless its dam cold out. or the very select few that need it to run special
valve timeing stuff that need a specific oil to function. KB
Higher viscosity oil (10W-60) delivers higher thermal stability where as
lower viscosity oil (5W-40) minimises fuel consumption and emissions by
reducing the energy required to circulate the oil. The correct viscosity
is specified by the manufacturer and is designed to optimise the
efficiency, performance and life of the engine.
SYNTHOIL LONGTIME PLUS | 0W-30
Special development for VW, Audi, SEAT and SKODA petrol and diesel
vehicles with service interval extension (also pump jet engines).
The fully synthetic low-viscosity motor oil from the Longlife 2
generation keeps the engine perfectly clean. Exceeds the high Volkswagen
test requirements. Reduces fuel consumption in one of the toughest
consumption tests in Europe (CEC-L-54-T-96/ MB M 111) by more than 2.5%
as compared with the specified reference oil. Fast cold-start oiling
provides excellent engine wear protection during the start and warm-up
All-year oil for petrol and diesel engines with and without pump-jet
technology. Specially developed for vehicles with service interval
extension (German abbreviation: WIV) from Audi, Volkswagen, Seat, Skoda.
Tested safe with catalytic converters and turbochargers.
No problem. But I really want to know why 40-weight oil was a proper
choice in HOT weather (80mph on a slight uphill across the Mojave in
August, for example) a while back but now isn't even an option.
Likely someone could make a 40-weight oil with the correct additive pack for
that engine, but nobody does, because it would be of very limited use.
There aren't a lot of people in the Mojave at any given time.
They make the oil that is usable over the widest possible applications with
the correct additive pack.
