Why wouldn't GM require an early oil change if this was the case? I have cut a few filters open and rarely see anything significant. It is easy to examine the outside of the Vue's filter, and I haven't seen anything of interest so far.

Some people are > harder on their engines than you and your sister.... Until this year my Sister's normal commute was 2 miles one way. She essentially drove the car in 2 mile segments separated by long periods of time parked. This is pretty hard on an engine. I am easier on an engine than she by a long shot. > and some people dont buy quality oils. You need to define quality oil. If it meets the specifications set forth in your owner's guide, then it should be "quality oil." If it doesn't, then all bets are off and you certainly shouldn't count on the oil change indicatior. > Making a broad statement like that and expecting > everyone to have the same variables is a long shot. 4000 miles is the > limit I give any filter and 500 miles on a "fresh" engine is the limit > that should be given for both oil and filter. And you are basing this limit on your Grandfather's wisdom? You don't think the engineers at GM can size a filter to last 75000 miles? How about European cars that use the same size filter, but specify even longer oil change intervals (10k or more miles)? Engines are better today, oil is better today, filters are better today, fuel injection systems don't dilute the oil with excess fuel, the oil isn't contaminated with TEL, etc., etc., etc. - why do you think you need to stick to the same oil change recommendations that were in place in 1957? If anything, the oil change intervals indicated by the oil change light are probably conservative. > Besides that 100k miles on > that engine aint nothing.

I have never gotten rid of a vechile becasue of a bad engine. In the end, I dump them becasue they are falling apart around a perfectly good engine or becasue I am just tired of them. Why spend hundreds extra making unecessary oil changes? Who are you helping - the junk yard operator? I've have a 25 year old farm tractor with 6000 hours (roughtly equivalent to 200,000 miles)that has a good engine and I have never changed the oil more often than every 150 hours (roughly equivalent to 5,000 miles). This engines has been worked far harder, under far more severe conditions than 95% of all car engines. We all have to make our own decision on what is best. However, I think we are being brain washed by places like Jiffy Lube into believeing that we need to change our oil every 3000 miles (or sooner). I believe that 5,000 mile oil changes are mor ethan sufficient for 95% of all drivers. I also applaud GM for including an oil change indicator that is based on more than just miles in their newer vechiles. I believe if owners would use this system, they can save themselves time and money, while not reducing the useful life of thier vehicles. Regards, Ed White |

The reason I don't trust the light is it will go up to 7,000 miles
before it goes on (i've had it not reset when I've gotten oil changed).. in my book 7,000 miles is just way too long to go between oil changes. |

Mine has gone all the way to 7,000 or 8,000 YIKES! That's a bit long.

But why do you think 7000 miles is too long? Did you have the oil analysed after 7000 miles? I haven't actaully let mine go that far yet, but it is not becasue I don't trust the light. It is that the three times I have changed oil, I did so for convenience reasons (more than 6000 miles on the oil and it was a slow weekend, or I was getting ready for a long trip, etc.). I don't understand the reluctance to trust the oil change indicator light, or the belief that modern oil in a modern engines can't last longer than non-detergent 30W oil did in a 57 Studebaker. 3000 mile oil changes seems to be a uniquely North American habit. Ford and GM sell the same engines is different markets and specify far longer oil change intervals in Europe than in the US. For instance, in Europe the Ecotech engines have 20,000 mile maximum service interval instead of the 7500 maximum for the US. I believe they do use 5W30 synthetic oil instead of 5W30 conventional, but then they also offer more highly stressed turbo models. See http://www.migweb.co.uk/forums/archi...ex.php/t-17134 : "New Vectra features a flexible service indicator, which provides information on when servicing is required depending on how the car is used. Petrol engines require an oil change at 20,000 miles (or up to two years) while the diesels are up to 30,000 miles (or two years)." And we are worried about 3,000 vs 7,000 mile oil changes....geez. In Europe they argue whether 10,000 mile, 20,000 mile or 30,000 mile oil changes are needed. Regards, Ed White |

I agree with you about oil change interval (even though I use 3k
interval myself - brainwashing...), but not about break-in period. Advance of contemporary technology doesn't change the laws of physics. Being a mechanical engineer by education, I remember a college course about machine-cutting equipment and how to correctly break-in that machinery. Engines with their high dynamics and temperatures are even more sensitive to correct procedure of a breaking-in. You need a good magnification to be able to see in the oil particles, which are a product of accelerated wear during break-in. A properly conducted breaking-in and a proper maintenance could provide a quality-manufactured engine a life span of 1,000,000 miles. Removing break-in procedure greatly reduces a life span of an engine but still it could be well above 100k miles. I don't think GM wants an engine last 1,000,000 miles, and most people won't complain if it lasts about 200k miles. Also, GM doesn't require early oil change, which is a part of break-in procedure, because we live in the society where even slightest inconvenience is very undesirable and could steer a potential customer to a competitor.

Well put Jerry. Thats the reason why I dont recommend synthetic oil for the first 6000 miles. It never breaks in right. |

I agree with this approach. I think 3000 mile oil changes are a thing of
the past. I don't think GM would recommend something that would harm the engine with the competitive auto market today. Doubt if I'll go till the light comes on but 5K sounds good to me. John "C. E.
