I had an oil change done at the dealer and Asked for FULL SYNTHETIC 5-40. What they put in was Valvoline Premium Blue Extreme 5W-40. I know that it is FULL SYNTHETIC or so they say, but is it OK to run in a 2005 SAAB 95 with 70,000 miles. It is a Diesel Oil.. I have always run Mobile 1 0-40 and had it changed every 3-5 thousand. never over 5. What i am asking Is that Oil OK and or will it harm the engine or turbo. If it is OK or maybe benefits the engine then I will stick with them for oil changes....
The car is a 2005 SAAB 95
70,000 miles
I live in Maryland
Most trips are semi short to long
I don't drive it hard just fast
The manual states Mobile 1 0-40.
No engine problems, not burning any oil.
Thanks for all your help.
