Default 5w20 Oil in PT

I recently had my oil changed in California (I live in the mountains of Arizona where it doesn't get really too hot in the summer). I was spending the month over there so while there oil change came due so took the PT in for an oil and filter change.

Two weeks later at home I really looked at the invoice I was given and it showed they put in the 5w20 oil. I called back there and they confirmed they did but that the PT could use either the 5w20 or 5w30. I told them I hadn't heard of that, and that the oil cap itself says 5w30. Well, not much I can do 400 miles away. I have now driven about 600 miles so far on the thinner oil and all seems okay, but still.

What I wonder if this thinner oil will be okay until my next oil change in 3400 miles or if I should break down and have the oil changed again here to the correct weight. Opinions? I did find a forum in this group from 2013 with several back-and-forths on this issue, but far too many different opinions, nothing difinitive. Thanks in advance.

Your "perfectly" fine with the oil that is in your 2.4 Chrysler engine used in the PT Cruiser !

Personally I like the oil filler caps that DON"T give any information except the words OIL!


BTW not that is matters but the word "viscosity" is the better choice of word regarding motor oil. The "W" means winter not weight.
Oil does not change its viscosity either it just gets dirty.

Now I trust we will all debate all this yet again??? hahahahaha!

Thanks, Lynn, I feel a lot better. You have really helped me in the past so this shouldn't be any different. At least now I'll save a few dollars in not changing the oil again.

If you can, run 0W-20. It's going to be a full synthetic and will give you more power and fuel economy (marginally but measurable) . But, don't use a 0W in california or arizona

I think the 0 stuff is worse if you have a leaky car. It pours like water at room temperature, so if you have a car that leaks while it sits, it can dump it out faster. Of course, we should just fix the leaks, but...

If that was true, sludge wouldn't exist in cars.

Our na2.4l auto has been loving 5-20... gets on the freeway great! But we also change it every 3 months. Shoot you could use 0w, but only if i was racing it- and it would get changed the next day....warning, you will not win the indy 500 in any pt...

Do some very in depth research about motor oils and contact oil refineries and oil distributors about this exact question about viscosity.
Try not to look on the internetoftenwrong for information.

Look up the Websters definition of "sludge"!
example of one: dirty oil, especially in the sump of an internal combustion engine.

Not sure where this is even close to accurate?

My other CA (federal approved standard for sale in Ca) car it is recommended to use 0W/20 motor oil.
As for measurable engine output using 0w20 vs most other close viscosity motor oils and or fuel economy ...claims, they all make for great sales pitches but in reality that about all.

I actually did a base line test run 0w/20 MAZDA motor oil on a new engine and later after 10k miles using 10w30 Mobil 1 . Hate to tell you but got more power and better MPG.
If you are quick to respond you may know why?

Really once again in a PT Cruiser you can use 0w/20, 10w30,10w40, etc., and even in some cases 20w50 and they will all perform well in most all states. Exception might be Alaska.. hahahaha!


ITSA PT Cruiser they are born to be abused and not flinch! Just keep up with regular oil and filter changes.

An oil leak is an oil leak. Car or bike if the seal or gasket is bad it is going to leak no matter what motor oil you use.

Your comment IMHO (and even can be shown through better information) is really OLD SCHOOL MYTH!!!!
