The 0w part is only relevant when cold starting. Getting a 10w just means you can't use it when it's as cold and that it's probably a cheaper oil. The 0w oils will be much more likely to be proper synthetics. It's the 30 or 40 part that's relevant for actual driving with a hot engine. Either will pr...

If its a turbo car, for longevity use full synthetic. OIC of 7500 works on my turbos, the best way to settle what is right for you is use 5000 miles if you don't want to test, use Blackstone after 5000 miles and then adjust per their report. Your hot climate isnt that hot to the motor, which runs at...

If I were you I would not deviate from the warranty booklet or maintenance schedule booklet's recommendation on oil weight or change interval. Your engine has a READ Rear Engine Accessory Drive, and a metal timing chain both located between the engine and transmission and both kept lubricated with t...

June: a 0w* will be thinner when cold starting compared to a 5w* or 10w* but the same when the engine is warm. It's not thinner at operating temperature. It's more fluid at cold temperatures which means less wear on a cold engine. The second part, 30 or 40, is for operating temperature and it's what...

Wow. That car doesn’t owe anyone anything, does it?

Wow! For a transmission proclaimed as junk by everyone not able to run beyond 40K without a rebuild, here is one driven 60K slipping! Also still going at 325K! IMPRESSIVE... I agree with Abscate that car has done it's duty. June

Indeed a true testament to the Car's refusal to quit. It will enter Volvo folk lore. One thought for future ownership - for anyone looking at this thread. Used parts can be had for nothing. Recently I saw one poster using with great success discs and rotors. I wager you could have done your suspensi...

I never upgraded to a 3.0 T6 which is the 3.2 cousin. I just didn't like the AWD as the only option with T6 and the READ system worried me. Just like the current 2018 T6 AWD mandatory, so I still drive my 2004 T6 daily. You found what I was talking about. Apparently 0WXX is listed. The attached phot...

Love the white color, quite rare. Was the timing belt already replaced ? As for the oil, you don't have a turbo so a good mineral would be fine. Synthetic would be mainly for an extended oil change interval. But very important check first if the car did run on mineral before. switching to synthetic ...

To add, (or repeat) what others have said... The first number (0W or 5W or 10W) is the cold viscosity. W is for Winter. If you think you're going to see very cold temperatures before the next oil change, then worry about it, otherwise probably not. The second number is the viscosity at a fixed highe...
