I was wondering if anyone could help me figure out what motor oil to use in my 2017 Volvo VNL 670 with the D13 engine. I've been using Shell Rotella T4 10W-30 for a while and I like it. I've been hearing some good things about Shell Rotella T6 synthetic and wanted to give it a try. The only problem is, shell only sells the t6 in 5W-40, 15W-40 and 0W-40. So in my case, which grade should I use for the best performance and best mpg.
Thanks
Oil changes often?

Since 400k I have used Rotella T6 5w-40. Think a couple of others use the same oil.
Farmerbob1 and 8withaV Thank this. -
If T4 lubricates it fine, why worry?

Rotella T4 is $12.47 a gallon at my walmart. 5w40 T6 is $18.88 ... free delivery so I do not have to haul it.
After break in I changed from conventional to synthetic in my ol yellow 2WS. I bumped from 4 weeks 12,000 mile changes, to 6 week 18,000 mile changes. Oil samples with both came back as good oil. Little higher soot on the 18k change. I would burn about a half gallon by 10k with the T4. The T6 doesnt really burn any.
With the interval change I figure I am money ahead at the end of the year. Better is fewer oil changes to perform
Out in AZ during the summer I would lose 10 plus lbs of oil pressure with t4 when the temps were high. T6 may drop the needle 3 or 4lbs. Have yet to run cold weather. But I idle, so no cold starts.8withaV and Farmerbob1 Thank this. -
18,000 on t6?
I’m getting an average of 28,000 for trucks without bypass system.
With a bypass system, I am getting an average of 38,000.8withaV and Farmerbob1 Thank this. -
