manufacturer recommended transmission oil for 2005 Volvo S40 Google Search

Please follow the experts recommendation . In Automatic transmissions are not using thick oils. Only special and manufacturers recommended oils are used. If you will not change it you will come surely to an unexpected and not worthy situation. Proceed as you been told . Renew the oil and filter and I again inform you to use the specified oil from manufacturer and nothing else.Also it is better to put into your automatic gear box if you can find the " Wynn's Automatic Transmission Treatment. "It will help a lot.

If it has never been changed, I would recommend you get it done now, if you take it to a service shop, nothing has to be removed, the oil changer plugs right into the transmission lines. on the 3rd year, I recommend the ****** filter changed along with fluid.

Hi, you should use energy conserving oil from Mobil One or ELF synthetic that comes from a container stating, "designed for use in GM vehicles". You will save money on gas, on oil changes, sludge will NOT form inside the engine, and everything will last longer.

The standard oil used in newer vehicles is SAE 10W/30. It is OK to mix oil brands but not recommended to mix different weights. Please rate this answer, thanks.

sae 5w30 is the oil grade you will need to use

u can use premium unleaded for ur x3.

The recommended engine oil for that vehicle is 5w-30 engine oil.

get them from the dealer. THERE IS A DIFFERENCE IN DESIGN. all i will use are oil filters from the dealers. dont try to save pennies when engines can cost thousands. happy holidays

Yes, typically the recommended change interval is about 60-70K miles. Check your owners manual, it will tell you the exact interval.
