scheduled maintenance
It seems to me the recommended schedule of some items is questionable.
Every three months or 3000 miles for oil seems wasteful. Every 5 years for coolant? That seems like taking a chance. 100,000 miles for sparkplugs? They really last that long? Transmission fluid and filter change every 15,000 miles in Florida city driving otherwise only once every 100,000 miles. Personally, I think oil is good for 5000 miles easily. I don't trust coolant after two summers in Florida. Sparkplugs - no opinion. Transmission fluid - yes as recommended in Florida city driving. Anyone else making their own schedules? |

Agreed, unless you are driving a '65 Pinto on dusty roads. > Every 5 years for coolant? That seems like taking a chance. No problem with todays closed systems. > 100,000 miles for sparkplugs? They really last that long? Todays plugs will do that without breatrhing hard. Pulled mine on a '92 Eldorado at 118K and put them back in and got a different set for the Corvette. > Transmission fluid and filter change every 15,000 miles in Florida > city driving otherwise only once every 100,000 miles. That may be beyond where I'd go, maybe 60/70k on an automatic. > Personally, I think oil is good for 5000 miles easily. I take mine to 10,000 using synthetic ('05 LS2). > I don't trust coolant after two summers in Florida. Why? > Sparkplugs - no opinion. > Transmission fluid - yes as recommended in Florida city driving. > Anyone else making their own schedules? More specific answers could be given if you were to let us know what you're driving. |

I have one, only it goes under the name Mustang. He worked under cover for the government until he came out of the closet in '71, nearly dies in '74. Although he leaked, rattled, and squeaked he was never lost as he could follow the oil trail back home. Made quite a mark on the BBQ scene for a short life of 10 years. Are you safe walking "and" whistling?? ;-)) |

Oil Life Check out < http://neptune.spacebears.com/cars/s.../interval.html >. My old C4 is on that sked. Amounts to topping up the crankcase every 2K miles, change the filter every 3000. Drain and refill at 10K. I go by the DIC "oil life" indication for the C5, the truck and my wife's car (3.6L VVT/DI engine). To play it safe, I top-up regularly, change the filter at 5K and drain/refill when 25% shows up on the DIC. For all three, that looks like the oil is good for 10K. I cut that to 7500. |

Oil: agreed, I push it to 7,500 Trans fluid- don't mess with it. Every time I have, soo after I have trans problems. Coincidence??? Plugs...changed my LT-1 plugs at 106K when the OptiSpark failed. Wores too, but till I dripped coolant on Opti all worked fine. My Explorer has 146K on the original plugs/wores. Still 17 MPG, just like brand new... Coolant, there too, until originaal installation is damged (leak) it lasts a good long time. But changing with fresh can't hurt every couple of years, check specific gravity.

Only exception was my C4 which had multiple injector failures and an assortment of lean and rich mixtures from cylinder to cylinder. Plugs were a mess when I changed the injectors at 60K miles. pj |

On my wife's BMW, the dealer says you can go 15,000 on the synthetic oil. I
change it myself at 7500 miles. About $35. She also only puts about 3500 miles on the car a year so this oil change is once every year.

Engine seldom sustains a good operating temperature. I had run her last car on conventional oil. New concern is with the hygroscopic character of synthetics; so, I change it at six month intervals and am considering four months (which gets a bit ridiculous.) Alternative is to take her 'land boat' out on the road every week and give it a proper workout. Savings on oil would more than pay for the petrol. |
