Motor oil question???

[jambo101]

Regular manufacturer oil change intervals will keep that engine running well past the time when the body is covered in rust. so going overboard with the increased oil change schedule is just throwing your money away.
The only thing the oil does is lubricate the Big ends,small ends ,rings, cam shaft and valve guides, items that most people never have a problem with in the normal life of the car.
Rust is more your enemy, getting the car rust proofed or oil sprayed will be what adds years to the life of your car,Up here in Canada there is a plethora of outlets dedicated to getting the protection on to your car.
I use a yearly spray from a chain called Krown,cost about $100 per application., in the USA Carwell seems to be the place for corrosion control

If no Carwell closeby check your yellow pages under "Rust and corrosion control"

I'm a fanatic about keeping rust away,esp. in winter.I'm always at the hand held car wash cleaning the underside for a LONG time.People look at me like .I just laugh at their rusty/crusty car underneath...

I've always used the 15,000 mile extended protection Mobil 1 because I've always put a lot of miles on my Yaris. I'm now at 112,00 miles on the car and just did an oil change. Time has kinda flown by and money has been a bit tight since, so the last time I changed oil was around 88,000 miles. My first oil change was at 5000 miles and it was conventional oil done at Wal-Mart because at the time I had started a new job and hadn't relocated yet, beyond that I changed oil at intervals between 12k to 16k. I've used Purolator or Mobil 1 oil filters.

So take that as you will, I don't think I'd recommend the 24,000 mile oil change interval I just went through, but I'd be comfortable with 15,000 miles.
