Motor Oil Viscosity

In the U S South regions where the temps in the summer time reach 100°
- I hate the idea of using 5W30 wt. motor oil - even tho it is a factory
recommendation.

what do you think?

The only way to find out is to get the used oil analyzed several times
while alternating between 5W-30 and heavier oil, but I've been told it
takes at least 6 analyses to get statistically meaningful results.

I used to drive a VW Rabbit (Golf) in southern Arizona with Mobil 1
synthetic 5W-20 and changed it every 10,000 miles and had the used oil
analyzed. The wear numbers were always low, and the engine had 150 PSI
compression when I sold it at 140,000 miles. VW recommended heavy oil
for this engine, straight 40 for most of the year, and they considered
even 20W-50 too thin. So a much newer design engine should have no
problems with 5W-30, especially in a cooler climate like yours. Also
not just Ford and GM but also many reputable car makers now recommend
thinner oil, so I doubt it's bad

Your manual normally gives a range of acceptable motor oil types or
viscosities
depending on the type of driving, temperature, etc. I think it is perhaps
wise to
stick within those recommendations, particularly if you have a warranty in
place.

What is your basis for hating the idea of using 5-30 engine oil.

I'm trying to understand why you would want to choose to ignore the
information in the owners manual. Possibly it is because you think the
collective wisdom of a few usenet group posters outweighs the
collective widsom of the petroleum, chemical, mechanical and
mettalurgical engineers employed by car makers and oil companies.

I think you need to think.

What gets hotter, the ambient temperature in Texas, or the
burning gasoline?

If you're that concerned about it, use a synthetic oil rather than go
thicker. I'd only go to a thicker oil if you actually have an oil
pressure problem.

In the last few days, that might be debatable, Aarcuda;>)

5W20 or 5W30 oil will save a few drops of gasoline during the first few minutes of driving. 20W50 will keep keep your bearings and camshaft lobes from wearing out after the oil thins out because it is running at around 200 deg.F. It's your choice.
