My 09 Sierra recently had a new engine installed (due to a defect in cylinder no#4)
Anyways I am thinking about changing oil this coming wknd as my new engine will have approx 800-1000km's on it and in my opinion it is due.

Just curious what some recommendations are for an engine that is not fully broken in yet?
I do not want to leave the oil that is in there now as most wear products have more than likely contaminated it plus my new engine was not a complete drop in, the intake had to be replaced as well as a few other components so there is a good possiblity that some dirt entered the engine?

What's a good conventional oil, not looking to use synthetic for at least 5000 miles.
Thanks

Agree!

Take your pick of any of the major brands and you will be perfectly fine. I hate to admit this but the first oil change on our new 6.0 in our 2500HD I used Peak oil and purolator classic filter because it was on sale and I knew I wouldnt have it in there long anyway. After that came out in went synthetic.
 
Thanks everyone!

It seems ironic to me that Mobil 1 wasn't mentioned as it was one of the best oils out there (at least I thought?)and Pennzoil use to be one of the worse (at least I thought again?)

Is it that Mobil's quality has decreased or is it because other oil's like Pennzoil have increased their qualities?

I planned on running Mobil 1 synthetic after my new engine has reached 5000 miles but now I am not so sure?
Thanks.

You'll be fine running Mobil 1 synthetic. Alot of people here run it. I ran it for years with "0" issues.

You can absolutely use the synthetic NOW if you want and do zero harm but if it bothers you then Pennzoil Conventional or Castrol GTX are very good conventional's.

Your thinking is wrong. Mobil 1 is hyped and Pennzoil is shot down with myths. Both are very good oils (as is pretty well everything else).

If I was going to stick to one oil I'd go with Pennzoil. In my Silverado 4.8l V8 the best oil for it (IMO/used oil analysis) was Chevron 5w30. Pennzoil was 2nd. The few runs of Mobil 1 were less than impressive and not the best value. It has been suggested that Mobil 1 is different in the past few years.

I would get some miles on the new engine before I started spending $$ for expensive oil. You need to make sure all is okay with the new engine.

For me, what I do is follow the OLM with a good conventional 5w30 and call it a day. Millions of Chevy/GMC trucks are doing that and running fine.

Sorry to hear that your first engine had a issue.

Take care, Bill
 
Thanks again everyone, looks like I am going to run some Pennzoil conventional for the time being(plus it's on sale like what was mentioned above!)

I believe I will switch to syn after another oil change or just before winter hits this coming fall/winter?

I was really hoping to run Mobil 1 0w30 (green cap) but it is unavailable in Canada at the present moment for some reason?

If it is still not available, then I am going to consider another syn brand?(depending on what some say about a particular brand on here?)
But I take it Pennzoil Ultra is probably one of the better synthetics out there now?
Thanks again.
 
Irv,

For your engine there really is no "better" oil out there. QS, Pennzoil, Mobil, Valvoline and any of the other oils are going to do the same in a 5w30 weight.

Follow the OLM and run whatever is on sale. You have to do that to keep the 100,000 mile warranty in effect anyway.

Most people who are going to say brand x is just a following, nothing on fact. Fact is any of the 5w30 oils that meet what you need in the manual WILL do just fine.

Take care, bill

Thanks Bill.
I know what you are saying but you yourself said it above, that you had less than desirable results running the Mobil you used??
(The few runs of Mobil 1 were less than impressive and not the best value. It has been suggested that Mobil 1 is different in the past few years.)


Myself, I am looking for better results than that as I usually do long OCI's, which I thought Mobil 1 provided?

Right now, as it stands and from what I read, it seems the Pennzoil Ultra is the bet oil for long OCI's and the best protection?
Maybe I'm anal, but I do want something that is above the norm as far as protection and wear go as I do keep my vehicles for many many years.

He's just saying that he could not get his money's worth out of it for the difference in cost for the utility that it delivered. If it offered no reduction in consumption (if any was experienced) ...or offered higher consumption for that matter.. or could not go a distance to make up for the added cost, it made no sense to use it.

While I find Bill's usage profile totally unique, the evaluation format is sound for anyone. Don't pay any more for anything than you have to, just check your scale of economy. The odds of longer engine life over one oil over another are never going to be tested since they're outside of even obscure ownership ranges.

So in most cases... it ends up being an "oil life" issue. How long does this stuff work within my process variable?
 
Don't use synthetic...not needed.. use Pennzoil conventional. The new stuff is about as close to syn as you can get while still conventional

Absolutely agree. No need to use synthetic as long as the engine is in warranty and oil changes are required according to the OLM, which is programmed for dino.

I'm looking forward to the near future when all this synthetic craze all ends. I think a "true" oil nut would use a conventional like Pennzoil conventional realizing he is saving so much money...running a conventional oil that will go the distance if one chooses to extend, and saving the synthetic oil for the cars and climates that really need the stuff. But, as they say, opinions are like "you know"..everyone has one. LOL

Irv, A few questions;

1. What is a "better result"?
2. What is your driving style?
3. What is a long OCI to you?

I keep my vehicles many years and put a LOT of miles on them. Once I get to a certain mileage then I sell them to a family or friend who gets more value out of them. How many miles am I talking about? 250,000 miles plus. My 1986 Jetta had 394,000 miles on it when it was totaled. Just passed Dyno smog and ran great. Have a 1982 Toyota truck which this summer will be its last year with well over 300,000 miles. Why? Rust and it will not pass safety. 1996 C1500 Chevy with 4.3l V6 has over 250,000 miles. 1993 Dodge Caravan 3.8l V6 around 240,000 miles. All run excellent and are dependable.

Let me know YOUR conditions and what you are looking for.

Thanks, Bill
