Which oil for a spotless engine?

The next time you go to the dentist, tell the doctor there's no reason for him to clean his dental instruments; you want them UNcleaned.

Made my living working fleet and rental repair such foolishness is not necessary. Dental work and engines aren't the same .

I know this is the PCMO forum, but I am surprised no one mentioned any of the main HDEOs

Amsoil Signature Series changed every 3k with OCOD.

that would be such a waste of a great oil... why not just go pick up some PYB if you're going to do 3K changes....

What does one have todo with the other

Absurd

It was 10W-30 right? If it wasn't, then you are NOT Merk!

 

[Merkava_4]

Yes absolutely, 10W-30. I got a quart bottle of it sitting next to my computer right now. It's sloshing around very freely; almost too freely. Why people think they need anything thinner than 10W-30 is beyond me.

Does your Buick have the 3.8?

Aren't they either spec'd for 5w30 or 10w30?

 

[Merkava_4]

Mine is the 2000 model year. It's spec'd for 10W-30 unless you get below 0*F.

It's a BITOG thing. If 10W is good, then 5W is better.

 

[kschachn]

So you both are saying as a generalization, 5W- oils are thinner than 10W oils?

But you're still using a watery ILSAC 30 grade.

It says on the back of the bottle - "Meets or exceeds the performance specifications of: ILSAC GF-5, API SN, ACEA A5-02, GM 6094M and GM 4818M, Chrysler MS-6395."

I don't know what all that means, but it sounds impressive.

 

[Red91]

I'm not a believer in synthetic at all, but QSUD seems to be a good oil. I think you'll be happy with it. Really should be using a non resource conserving 30 or 40 grade though.

 

[tig1]

Do what I do. M1 0-20 at 10K OCIs.

If my car calls for 0W20 should I use 10W30 instead?

For me it would depend on what the engine sounds like. If the engine was noisy on 0W-20, I'd change it to a 30 weight. If it's whisper quiet with 0W-20, I'd leave it in there.

Amsoil changed every 7500 miles would probably do the trick.. Darn expensive though. But really and seriously Mobil one "full" synthetic changed every 6k miles or Pennzoil Ultra if you can find it.. Like finding an alpine colored deer in the woods. Either one of those would most likely result in the spotless motor result. And 400k miles is a heck of a goal. Thought I was ambitious for wanting to get 300k out of my car.

ILSAC includes watery 30 grades, Merk.

What isn't impressive is them quoting a 12 year old ACEA spec, mind you.
