I have 160,000 on my 5.0 Mustang, and it runs quicker now than it did with 70,000. Will be replacing engine, transmission, rear end,brakes, and suspension soon anyway though...(performance reasons) I drive it everyday like I stole it, but I take care of all the maintenance exactly when it needs it. I've never had it not start, I've never been stranded, its been 10000000% reliable. I've used way too many different brands of oil... from Valvoline synthetic, to Castrol synthetic, to AMsoil, to Mobil..... I've currently decided to stay with Mobil1 15w50.

[Cool] Wife's 99 Grand Am, almost 60k, no plans to trade, M1 every 5k. My 02 Ranger, 33k, has a year left on the lease [Eek!] and gets M1 every 5k too 'cause I'm a car nut. [Big Grin] More for the alledged mpg benefits. [ February 27, 2004, 01:58 PM: Message edited by: JohnnyO ]

I usually keep vehicles 100-150,000 miles. I use synthetic in my gas engines at intervals from 6000 to 10000 miles. I do long trip lengths in warm to hot climate and base my change interval on cleanliness inside valve cover, and oil pan capacity vs. fuel consumed. I used to let my 99 Corolla go 10K on synthetic based on 4 quart oil pan and 36 MPG fuel economy. The engine was spotless inside at 120 K miles.I plan on going about 8K on my current Camry based on 4 quart pan and 30-32 MPG. I will monitor conditions inside valve cover to ensure my schedule is adequate.

We have four . The 1992 40k miles , 2002 24k miles and 2004 500 miles . Expect 300k each due to design and maintenance care but run synthetic anyway . [Smile] The 4th , a 1974 model gets 15/40 Phillips Racing Blend . All will be kept in the Family . The Wifes 02 will be my beater soon if she gets her way . [Smile] None burn any oil . When these motors start burning synlube it's time for a rethink on what goes in them IMO .

I have a 2000 Ford Ranger 3.0L, auto trans, 66K miles, and I'll be keeping it for a long, long time. At 60K miles, I changed all the fluids and filters and put synthetic back in where it counts, such as the differential. Runs perfectly and has never used any oil. Only problems have been a VSS sensor failure and DPFE sensor failure. And I know it will last a long time because I let Terry keep an eye on it for me [Big Grin] [Wink]

My truck has 57k miles on it. I plan on keeping it until the day I die and then I should be buried in it. My crown vic has 136k miles on it. I plan on keeping it forever too. Would make a good family car and someday I hope to have enough money to make it go faster. My 1994 Ford Aspire (daily driver because of good MPG) I plan on keeping until it has 202,000 miles on it. Although I plan on putting in a larger engine once I get a job. If I have this car for 100,000 miles in gas alone I will save roughly $4688 compared to my crown vic. Now it's to the point that I think the aspire needs synthetic. I think it would die on dino oil. The lady before me didn't take good care of it. It used to get 40 mpg on the highway and now I get about 32. Sometimes I have a lifter, rocker arm, or valve that sticks on cold start up. My compression is down to 165 to 170 psi on all 4 cylinders. Luckily it stopped burning oil when I switched to AMSOIL. After 4053 miles my oil had 2.5% fuel. I had really good wear numbers, but I wonder what they would have been if I had used a cheaper oil.

1999 Saturn SL, 186,000 miles. I plan on driving it at least to 250,000 miles. If it continues to be as reliable as it has been so far, maybe longer.

I have been using M1 10-30 in my wife's 1998 Montana since 36K. It now has 66K. I change the oil every 6 months. Plan on keeping the van until the paint falls off. (Being a GM product, that could be tomorrow, lol). I have also strictly used pf47 filters.

Hello members 2000 5.2L Dodge Ram Q/C Sport 4x4 48,000 Km's on it currently, purchased @41,000Km And going to drive it till the wheels fall off! Realistically a previously owned Dakots hit 260,000 Km and was in need of major repairs so I cant see why with good maintenance habits I cant expect 250,000 - 300,000 Kms out of this one [Smile] Keep on truckin' [Smile]

I'm currently at just under 99k on my 95 Formula, and would like to get rid of it in 3 years to buy a C5 Corvette, however if I can't get one at that time, I'll keep driving the Firebird until I get one. I drive about 18k per year, so in three years I'll have 153k on it. So I need this engine to last as long as possible, especially since I drive it very hard. I treat every engine as if I'm going to own the car for 10-15 years, just in case. When I do get the C5, it'll be a keeper for a very long time, at least 10-15 years. I'd only sell that one to pick up a C6.
