that is, car oil...

an issue of great importance.
i hope we can follow the issue and get polite, positive messages.

 

I imagine this was an interesting article 20 years ago when it was written. Last year I bought a new VW Tiguan and this year a new Atlas. They both recommend Castrol synthetic at 10,000 mile intervals. I think the filtration info is still revelant.

 

there are facts that are always relevant, especially for some that did not know a thing about them, no matter when they were released. and ferrari is selling their latest with still another brand-but all are synthetic.
and there is a study that also is to be considered despite when it was released: https://www.northamericanmotoring.co...g-results.html

 

Another one?!
I'm about two thirds through the first one and probably won't be finished with it before dark.
Now I know why the Walmart synthetic (that I put in my focus) is so incredibly cheap..
Still, appreciating the good reads. I wonder if the synthetic oil is better for undercoating than the conventional. That is where my drain oil goes...

 

Ha , I used to do that yrs ago , what a mess !! Also used to under coat w/ linseed oil , inside panels ,under inner fenders , almost the whole underside . Once that dries to its flexible state , you can't cut it w/ lacquer thinner ! Wife really didn't care for the smell of linseed :0(

 

Linseed oil?? Never thought of that. I kinda like the smell.. There's something called Fluid Film that's supposed to be the rage now. A little expensive but so is rust repair.
Getting off topic I guess. I've got some more reading to do here.

 

Boiled right' not raw? Linseed that is.

 

.


UN FRECKING BELIEVEABLE.. Surely you ppl are kidding. Old oil, pollution, get a life about spreading all that crap on roads all over. I have a well for water! What DOUCHE would do that today!


.

 

Yes boiled , it dries fairly quick .

 

For the sensitive city boys , the roads were dirt back then & the towns would spread oil on the roads to keep the dust down .
Anyhow , I always put plastic down in a garage w/ a concrete floor , let the oil drip off , then folded it for the garbage truck .
Our well has always been better than city water .

 

Most if not all undercoating on cars these days is rubberized. It won't absorb oil like the old asphalt type would.
Linseed oil on metal would be good. It is edible. I use the raw on exposed wood on my porch and also on the kitchen cutting boards to help preservation. You can add the mold inhibitor from the local paint store on the outdoor stuff.

 

I guess maybe I helped get this topic diverted -- my apologies .
The best spray on undercoating I last used & I think I've a couple of gallons left , is a liquid wax that's dries semi hard --- good stuff , no odor , & was cost reasonable !

 

So we started out talking about oil on the inside of the car, the engine and now we are talking about oil on the outside of the car, the body. I digress, and it only took 4 posts. Just sayin. Love forums.

 

agree, but that is 1 of the things that, even out of context, some times bring knowledge anyway.
as long as is positive and done politely...

 

So we could recycle the cars body panels by eating them, good to know as there will be plenty of iron in the meals. A balanced diet would need you to eat the wheels, that’s not going to happen as rubber is just too chewy. 😜

 

i prefer the lower A frames - they are dark meat.

 

I would like to try the wishbones as well. 😉

 

You guys are going for the red meat! Mercy please.

 

when i started this thread i was thinking on MOTOR oil.
so, lets go to the link that i posted; https://www.autoeducation.com/autoshop101/oil_bible.pdf
please polite, positive and to the point.

 

so, to get back to the subject, here we have this data on why we use synthetic oil
