Hello -
I was just wondering what the best oil recommendation is for the V70 station wagon, 1998 - I live in Miami where it's hot and hotter.
Brand names are welcome too.
Thanks !

 

Any Brand name 10w/30 full synthetic will be fine for Miami temps. Change at about 7500 mile intervals unless you do a lot of stop and go, then maybe 5K miles.

 

You can use a 15W40 as recommended in the owners manual. It's a little thicker and will give you a little more protection. The manual doesn't list 10W40 but that would be a better choice too if 15W40 is hard to find in your area or it's more expensive.

Full synthetic with a good filter. You cab go with any brand or also look for auto parts stores house brand. At times autozone, napa, oreilly will sell their own branded oil and a filter for really cheap. Stay away from Fram filters as they have been know to cause lifter noise on start up.
I use a Bosch filter, people also recommend Volvo or Mann brands.

Engine Oil
Ambient Temperature
Less Than 68F (20C) .................. SAE 5W-30 API SH/CD
-4F To 100F (-20 To 38C) .......... SAE 10W-30 API SH/CD
Greater Than 14F (-10C) ............. SAE 15W-40 API SH/CD

 

If I lived in Miami I would run 10w-40. I run full synthetic.

A little more important is the type of oil filter you use. Only use OEM Volvo or Mann filters.
