Why did my 99 Volvo V70 not start?
My 99 Volvo V70 station wagon with 89,000 miles would not start last week and was towed to the dealership. They advised me that the belt tensioner had broken and subsequintly bent one of the cylinder heads. I am looking at very expensive repairs and was not sure of my options. Has anyone experienced this problem?
What is the compression ratio on a V70?
The owner’s manual is quite clear on this. The non turbo can use 87 octane, the turbo needs 91 octane, minimum. My wife has an 04 V70 base model non-turbo 2.4L 168 hp. The specs page of the owners manual gives the compression ratio (CR) as 10.3. The compression ratio of the 2.5T 300hp is only 8.5, and the other turbos are either 8.5 or 9.0.
What kind of gas does a 05 V70 use?
Our ’05 V70 with 2.4 (non turbo) has been doing fine burning regular (87 octane) gas. It was a demonstrator/loaner that was purchased about 6 weeks ago and I’ve only pumped regular, so I can’t really make a comparison. As long as it doesn’t knock and continues to get about 24 mpg for daily commuting I’ll stick with regular.
Can a Volvo be driven with regular unleaded fuel?
So Volvo is not rulling out the use of regular unleaded. What I get from this is that these cars can be driven hard with AKI 91 fuel and probably the knock sensor would not detect any knocking which would initiate retardation of the timing.
