Suggested oil for high mile 1.6 N/A?

[Rabbit TD]

I also use the Rotella 15/40 which most everybody else does too and like they say, you can get it about anywhere.  I'd like to use a synthetic but the amount these things burn and they do even rebuilt or not and as often as we have to change it because of the soot I'd just stay with Rotella.  I've used it in all the VW diesels I've ever had.  I think Amsoil has some of the best stuff around and they have an oil or grease for everything under the sun but it's pretty expensive for these motors and it's so hard to get when you need it.
  Amsoil makes a 2 stroke oil called 100 to 1 and that's the ratio you mix it.  We use it in the National Park service in all our 2 strokes at that ratio and I've never seen an engine problem or even a bad plug in 6 years in anything yet .  And weve got a lot of weedwhackers and chainsaws that are used every day.  That's half the oil that any other brand is, most are  50/1 today.

Oil additives should never be used.

Never is such an end all statement.  All things may have a use if the situation is right.
As an example, before I married my wife, she drove a ford bronco II that looked great but needed some serious engine work. Low compression, super noisy valve train etc.  She had just hired a plumber to do a bunch of work at her place during a remodel.  When I looked at the bid I saw that he had waaay over charged her for the work. She had been straight up taken advantage of.
 Now it so happens that this plumber commented a few times about how much he liked her bronco that he saw sitting in the driveway.  He had never been there when it was running. I talked him into a straight up swap, bronco for the work.  He would test drive the car the next day and seal the deal.  I changed the oil that night with 20w-50 and added just about every oil thickening, valve quieting, smoke reducing additive there was. It was probably like 90w now .  That thing purred like a kitten.  The guy drove it the next day and accepted the trade.  When he was done the job, he got the truck, thinking we were both suckers and he was making out on both ends.  About a month later we get a call from this guy saying the truck was making a lot of "funny noises" and his mechanic told him it would cost over a grand to fix and he wanted his money instead.  I told him the new overpriced toilet leaked so I guess we were even.....

Still say "never"?

For good reason.

In the the case of oil additives, the only reason for their existence is to make the sellers money. "Snake oil"?

Yes. That was a very deceptive and dishonest act. I'll be sure never to buy anything from you and I'll warn everyone else of the same.

The scientific fact is: VW says use any oil in the appropriate viscosity range for your climate with at least a CF rating.  Since that's a 1980's rating we go with what's available today:  anything with a CJ-4 rating or better.

That includes oils like  Delvac 1 and Shell Rotella T.  Elf makes some, Amsoil makes some, PetroCanada makes some.

Delvac 1 is my favorite. Indefinite life if you change the filter at normal intervals and do an oil analysis. Easy starts in the winter and superior mpg from the reduced friction.

Ya know, you come accross as a mister know it all in a lot of your posts and make quite a few nasty comments along the way insulting members in the process.  Having all the information in the world and being the smartest guy around does no good if you cant get your message accross with out turning people off.  Why dont you tone it down a bit?  If you want to answer with some smart aleck answer you can just keep it to your self, if you dont want to respond, thats fine too.  If you want to "warn everyone" about me you just go right ahead.

or

X2 if you will.

It does seem like your upset with us. I like you but you don't seem to like us. That or your VW is giving you fits or possibly something else? Let us in, share your burden, we may be able to help.

To tell the truth Ive only been an active user of this forum a wet week and I'd be inclined to agree too.

My Dad told me that a long time ago he was going on a trip in an American car (boat) with a guy and it had such bad oil pressure that they could only go 35mph tops. So the guy stopped and got a bottle of STP oil stabilizer and that fixed it, they roared off just normal.

He probably had a worn-out Chevy with hydraulic lifters and old thin oil that would not pump them up properly - the STP "oil treatment" as they called it when I was a kid, masked the real problems by thickening the oil.

Yeah whatever the problem was it fixed it, I don't know what engine it was or how the maintenance was kept up.

Those old, loosely built Chevys are why there is 20W50 oil on the shelves.

Just about any older American engine is why there are things like 20w50 and STP..  I feel Ford was even worse for poor oiling..  There was a brief period in the late 70's / early 80's they used NYLON rotors in the oil pumps... Not even 90wt gear oil would get oil pressure out of those things... 


Now to the other end of the spectrum, I ran 5w20 and a wix racing filter the first winter I had the current VW...  After 3 oil pumps and several different brands of filters it was the only thing that woudl keep the pressure low enough so that the filter wouldn;t explode.. Hot idle it would carry 90psi on it.. Kinda neat when the poil pressure gauge exploded one night... Once it got about 10K on the engine it was fine..  Guess the clearances were too tight.. I'm back to rotella T 15w40 and a standard Wix filter now...  Shame the friggen block is cracked....

I have the opposite on my diesel caravan - I get 90 - 100 psi max oil pressure when cold this summer. After warm-up, I typically have 44 - 60 psi while driving and 20 - 30 psi while idling. This is with the Mobil-1 filter, but Rotella 30. I'm switching to Mobil-1 when I swap my pan to change the trubo oil return line. Got too much oil going out the turbo compressor seals.

[theman53]

The clevite bearing rep won't run anything but 20w-50 in his cars. Why? he says that the newer oils especially the sythetics vicosity isn't the same even if it says it is. I still run syns but besides my VWs the older chevys is what has had the most oil pressure of all vehicles I have had. Love the VW and chevy for that reason.

[maxfax]

That's really interesting..   I have clevite bearings in my car, the one that had astronomical oil pressure... 20w50 woudl have sent the oil filter into orbit just from cranking....

I haven;t head so much about viscosity issues, but rather the lack of zinc in the oil..  Rotella is one of the few brands that still have a decent zinc content..  After alot of premature camshaft failures a few years back (the brand or the installer of seemed to make no difference) Jasper Engines and I think it was Comp Cams came forward they they do all their breakin and testing with Rotella..  Personally I think it was just a huge lot of soft cores...

Chevy's never really seemed to have issues with oil pressure itself, but rather poor oiling tot he valvetrain.. The bottom ends held up well, but the cams and lifters would wear something fierce and requite the heavier oil to make enough pressure to keep them functioning decent.. By the late 80's they changed something to help this out...
