Has anyone tried out the Valvoline Guarantee on their Volvo? i have a 2007 s60 with 43,000 miles. I am just looking into it and looking for some thoughts.

 

I am not sure about what the guarantee that they provide is but i have had issues with Valvoline.I had them do a Trany flush and it almost killed my Trany.They used what they said was Volvo certified fluid but that was a lie. I ended up being standed ATF fluid and did not meet Volvo 3309 specs.It only took about 2 weeks before i got the Tranmission service required message.The first thing dealer did was check the fluid.I was JET Black. Valvoline then told me that the fluid they use is only to be used in NON Warrantied cars and That using there fluid will Void Volvo's warranty .If i were you stay away from them.
