Change to Synthetic Oil

I am going to change my oil before winter in my GC, six cylinder. It will have less than 500 miles. Is it ok to put synthetic in it at that time? I know the mileage is low, but old habits are hard to break. Thanks.

Re: Change to Synthetic Oil

I have a practice of changing oil & filter way before the recommended interval. My 2015 V-6 was changed at 1,700 miles and switched to Pennzoil Platinum 5w20 with Mopar filter MO-349. I changed it again at 3,500 with a new filter and synthetic oil and now I am on a 6,000 mile change interval. My brother-in-law is a master tech, he said an engine during the assembly and break-end has the most contaminants, by changing on a shorter interval you are improving the break-in period, reducing engine wear over time. I have used this procedure with great success, he had a Toyota Camry with over 300,000 miles with regular oil changes with slight oil usage. Still running strong today!

Re: Change to Synthetic Oil

DON'T change the oil so fast. Let things SEAT !!

Your motor will be fine. I do my first oil change at 5-6K (around half the recommended interval). This is my 3rd Pentastar and they didn't burn a drop and I had the oil analyzed about 3 times.

I then do 7.5K intervals. I've been using Castrol Synthetic.

There could be additives, or it could be a slightly lighter or heavier oil designed to help it break in better.

I've done the same as above and went to 230K on my Jeep and 230K on a VW. Both were running great when I sold them and didn't burn excessive oil. Which is a feat with a VW.

Yes, there is more contaminants in the first few oil changes and was confirmed in oil Analysis.

It probably won't really matter either way. But I lean a LITTLE closer to what the manufacturer recommends.

Re: Change to Synthetic Oil

There are a lot of cars that come from the factory with synthetic oil. No problems changing to it at 500 miles. Everything is already run in anyway.

That's not the question though. Some beleive you are better off letting things wear in a little while with whatever was shipped from the factory.

I didn't realize they run motors a few 1000 miles under load before they ship. That's news to me.

The OP asked if it was OK to change to synthetic. I did answer that question. Unless one drives like a church librarian, 500 miles is plenty to seat rings and valve faces. If you are a church librarian, the time for proper mating of surfaces is gone anyway.
Where did you hear the manufacturers run engines for thousands of miles?

Re: Change to Synthetic Oil

Synthetic oil isn't going to hurt your engine. Changing your oil ever day isn't going to hurt your engine. The parts are not going to stop seating because they have fresh oil. On the other hand, changing your oil early is going to make you feel better, not your engine. Your owner's manual most likely says you can use synthetic, but not that you should. Again, using it will make you feel better, not your engine. On vehicles with engines that benefit from synthetic oil, the owners manual will call for it.


Yes, people will brag that they use synthetic and put a lot of miles on their cars. People who put a lot of miles with regular oil just keep driving, they don't talk about it.


I read an interview a couple of years ago with an executive from one of the major synthetic oil producers. He said that only around 11% of cars have synthetic oil in them at that time, but it was increasing hopefully to 17%. When asked why it had continued to increase in sales, he replied, "Great Advertising".


BTW - some manufacturers do use 'break in oil'. I believe Honda still does, and they recommend that you do not do the first oil change prematurely. It isn't like the old days when break in oil was thin. Their's has additives that smooth and fill imperfections, or so they say.


As for metal filings and things that people want to remove, they are not much of a problem today. But say you do have something in the oil. With an engine turning at 1,500 to 2,500 revolutions every minute you are driving, if it was going to cause damage, the damage would be done, even at 500 miles.


IMHO - of course.

yes fine to do it early I did my first at 1200 with synthetic. the usefulness of synthetics is one of those things that will always be debated till the end of the earth. but my thought is if you can get Pennzoil's best ULTRA synthetic for about the price of regular dino, then why not. stock up the rebates good for 24 quarts.

Unless you are running with no filter it's not going to damage the engine.

Changing your oil every day can hurt your engine, if you believe some studies. Google it.

Using synthetic is no argument there. It won't hurt anything.

So the OP is sort of asking 2 questions. But it's pretty obvious these days Synthetic is fine to switch to and not many will argue against that. There are arguments its total waste if your gonna do intervals at less than 5K (some would argue higher). But the OP is mostly asking if it's safe to switch so soon.

I say it's not a good idea. And IMHO he more likely to do harm than prevent harm doing it quite so early. But in reality it probably won't hurt. But I'm arguing that you are erroring on the more harmful side than less. And I'm not arguing against it because it's synthetic. I'm arguing to let the factory oil stay in their a little while.

What you folks are saying is every motor that people go by the book on maintenance using dino oil is going to be toast. Just isn't the case. I doubt Chrysler would offer life time warranties and then prescribe how to ruin your engine.

Why don't you change all the Differentials and Transfer case after 500 miles while you are at it? Those systems don't even have filters. All your bearings are just grinding themselves away. Oh and change the transmission too.

Sure be on the conservative side. But 500 miles, no way.

I change all fluids early on new vehicles. Then again, I'm also the rare bird that breaks vehicles in during a 2-3 hour stint on a dyno.

Mostly they are discussing direct injection engines. But the primary issue is taken care of with the installation of a catch can. I know (I should say have read) that some manufacturers with DI engines make catch cans standard equipment.
