Auto Oil

[mitchthephoneman]

For all you do-it-your-selfers, what kind of motor oil you use.......

I use 1/2 synthetic and 1/2 regular along with a container of STP Oil treatment. I have been doing this for many years and have noticed a big difference in my engine smoothness and pickup......

And of course I only use HiTest gas, in my vans....

Full snythetic, Mobil 1

 

[mitchthephoneman]

how long do you keep it in for and what vehickle.......

 

[caudio51]

99 Nissan Maxima...usually go about 3K-3500K per change...Fram Filter

I have never heard of mixing synthetic and regular.
I have been under the impression that if you use synthetic (such as a Corvette) and switch to a reular oil it would cause a higher rate of oil consumption.

Mobil1 ever 5000-7500 miles.

When the oil light comes on, wait till the next day (50 to 125 miles later) and buy the cheapest oil that the gas station has. Have oil and filter changed each May (every 30 to 40K).

I use olive oil and a wad of gum. Seems to work for us.

 

[ATCDub]

Mobil 1 in the truck and the benz. 50K on the truck and 160K on the car (which is a diesel)

 

[DocLogic77]

I actaully done know what we use. We take it to the dealer and let them change it.

The cheapest oil & filter possible and change it once a year whether it needs it or not.













NOT!!!

Quaker State or Valvoline only, no synthetic . Good quality filters like Purolator. Have you ever seen the inside of a Fram? I have and I'll never put one on my cars again. I used to work at a parts store with a machine shop and I saw the results of various types of oil & filter use.

That is my plan- Have a 94 Plymouth Colt that I bought 3 years ago with less than 100K miles. Paid $750 for it. It now has 216K. Most economical car I have ever owned and gets just over 35 mpg.

Finally starting to give me a little trouble- early in the mornings and when humidity is high it spits and sputters until it warms up. Once it's warm, I fire up a cigar and enjoy the commute.

Mobil 1 Synthetic every 7,000 miles

191,800 miles on the 98 Caddy
118,500 miles on the Mercedes 560 SL
80,500 miles on the Navigator

No engine problems what so ever.

 

[AZsteelman]

Valvoline every 4K miles or so...

CASTROL makes a part synth and part convent. oil. Its about 3 bucks a quart, Ive been using it for a couple of years, smooth running engine.......

 

[caudio51]

Never heard of it

How often do you change it?

Now that I have heard of thanks to John Force.

 

[jcgoldner]

In 25 years of drving I've never had an internal engine problem. I change my own oil and use 100% PA grade crude oil with a quality filter and change it every 3000 miles.

Now that I have heard of thanks to John Force.

I think he drinks Castrol in his morning cup of coffee :rofl:

 

[schuellk]

Castrol Syntec is actually part Synth and part conventional oil.

As for myself, Mobil 1 with the Purolator PureOne filters, every 4500-6000 depending on the time of year in a 99 Jeep Cherokee (4.0L w/ 80k) and 03 Mazda3 (34k).

I had to do a lot of research into oil and filtration systems for the one project I've been involved with at work. The army has requested a central oil system for an entire truck so that everything can use the same lube and extend drain/service intervals if possible.
