2000 VW Passat 1.8L mileage: 96,000. I've seen lots of questions on your site regarding whether you can use 87 octane fuel in a car that recommends 91 octane premium. You reply to most of them that 87 is okay. But on a couple, you say to stick to 91. What's the differing factor in these? My engine is a turbo-charged 4-cylinder. Is it best to stick with premium fuel on any turbo, or is there something else to take into consideration? Todd.
have the same problem?
