Suggested oil for high mile 1.6 N/A?

[Pre95]

I don't even know what oil is in the car currently, other then that it's black.

I like delo 400 15w-40 with 1/2 a quart of lucas oil stabilizer, I like thick oil .

My latest mix was the delo with hy-per lube oil suppliment, I hate it. I used to cruise at 2500rpm and have 65psi oil pressure, as soon as I started using the hy-per at the same ratio it dropped to 45psi.

Next oil change is gonna be maybe a full quart of lucas .

[Rabbit on Roids]

you can run normal 30wt in these engines, and have almost nothing for oil pressure, then dump some lucas in there and have more oil pressure then you know what to do with.

[OM617]

If you add Lucas, you're using the wrong oil and causing damage.

Oil additives should never be used.

[carrizog60]

whys that?

[OM617]

They are useless at best, sometimes harmful. A quart of oil is already more than half additives. Adding your own on top of it can conflict with the oil maker's intended effects, producing negative results like foaming (Lucas), sludge (anything with PTFE) and oil starvation (any oil thickener).

The oil companies have over a billion dollars towards R&D of their oils, do you really think any consumer knows better than them because a bottle on parts store shelf says it can perform some miracle?

I really like good old Rotella 15-40. It is cheap and really does a good job. It is also rated for diesel, which no matter which oil you go with should say on the bottle that it is diesel rated. I have used the synthetic rotella and others, but on an engine that has any leaks it usually makes it worse. I basically don't like quaker state and castrol for brands and have usually always come back to Rotella or Valoline for conventional oils.
Whatever you like that is what you should use just make sure the rating is approved for diesel.

X2 for the rotella.  its stocked at most wal marts , super cheap,  and my 1.6 n/a with well over 200K on the clock loves it

[burn_your_money]

Rotella for me as well. Synthetic in the winter for easy start ups

[Dakotakid]

Walmart also carries Ford's Motorcraft 15/40 in the orange 5 quart container and I have been using this off and on. Last winter, it was like $2.00 less than what 5 quarts of Rotella pencils out to. I figured: it's good enough for Ford's warranty on their elaborate diesels! No ill effects in me cars.

rotella-t



the white container. for synthetics, it's eneos or royal purple. - rotella's "synthetic" is a normal group 3 oil, not a full syn.

What is the difference between normal oil and diesel rated oil anyway? Does it make any real difference if you use petrol engine oil in a diesel engine?

yes, it does.



a diesel rated oil is rated to suspend soot particals

[Vincent Waldon]

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.

I use Rotella 15w40 and I change it every 2500 miles.  I can hear a difference right after the oil change!
