No, the two are not unrelated. Some on here are talking about saving oil. There is no oil savings really to long change intervals. If you want to conserve petroleum, buy a car that really gets better mileage. It is very relevant.

Still no better or cheeper insurance for an engine than top quality oil changed just a little sooner than necessary. -- Posted via a free Usenet account from http://www.teranews.com

He says he changes his oil at every 3000 miles and that is what he claims is the secret to getting so many miles. -jim > > -- > Pork: It's the other white flag! > -- James Lileks ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =----

It generally gets driven less than 20KM at a time. It is often driven on unpaved or dusty roads. Temperature swings can be extreme. Winters as low as -30C, with mild spells of +10 intersperced, and summers ranging upwards to the mid 30s C. I sometimes tow a trailer,(just solt the 17 footer) and often run with a load, and often need to drive in urban gridlock conditions. Then occaisionally it gets onto the highway for a 145kph blast. I never sell a car with less than 250,000KM on it - have 340,000+ on my current 12 year old van. Last car I sold was 18 years old and in good condition, using less than a liter (actually, well less than 1/2 liter) between 5000km (3000 mile) changes. I will continue to change oil at least every 3 months. On average over the lifespan of this van, that would be closer to 7000 km per change.(GM 3.8). On the wife's car, it comes out to under 5000 km, and occaisionally it goes 4 months. It's 10 years old now, and we will likely have it for at least 5 more years. This is a fairly highly stressed small dispacement engine (Mystique 2.5L) . -- Posted via a free Usenet account from http://www.teranews.com |
