2004 Volvo S40 1.9 Turbo 122,000 miles
out Walmart Super Tech Syn 10W30
in Walmart Super Tech Syn 5W30 (of course with filter change!)
Second oil change recently and I am using Walmart full synthetic and 5W30 this time over 10W30. I went 6500 miles on the first change and it came out pretty dirty but still had some clarity to it, I think it was the additives doing it's job.
Engine runs very smooth all the time and the cost is not all that much. I bought my filters from an Ebay seller that has high ratings. Walmart want 26 bucks for a filter for my Volvo! $7.50 for Napa's filter where the Ebay filter were 3.50 each when bought is threes.
Since Winter is a bit tough on oil with very cold starts. I will change in the Spring, I expect the mileage to reach less than 5000 miles.... at a 1000 miles per month.
I will be changing oil on my Nissan soon and will use Syn for that also....
