The AceyMan

dear a.a.h-

Just took delivery of a 2004 Sonata GLS (Pkg 5A) last week. We
really like the car (first new vehicle) and I'm looking forward to
breaking it in right and taking good care of it.

I see that the manual doesn't specifically state what multigrade
weight comes installed or what weight to use.

I live in Atlanta so temps are 0-15c in winter and then 20-35c in
summer. I was planning on using 10w40 but perhaps 10w30 might be
best? Any educated tips appreciated.

[BTW, my first change will be at 1200m with a top dino-oil (like
Castrol GTX), but then after full break-in I plan to use Mobil1
thereafter.]

TIA--

Either one will do the job, but I would base the choice on the type of
driving you do. If you're doing a lot of commuting in heavy traffic
where the engine gets hot enough to turn on the cooling fan, I'd go with
10W-40. If you do mostly highway mileage and other driving where the
engine stays cooler, 10w-30 will suffice. Neither one is going to be a
problem, so it's not worth being too concerned. In the winter, you could
switch to 5W-30 or even one of the new 0W-30 or 0W-40 oils which will
improve your gas mileage somewhat.

Oil technology and engines have changed considerably over the years and
recommended oil weights have gone down. Anyone need any 20w-50? I've got
some that I'll never use.

The factory fill is 10W30. There's a chart for selecting a grade in the
manual, but if you live in the continental USA, make it simple, put 10W30
all year round.
