Oil type 3.6L (5w-20 or 5w-30)

[Basecreek47]

I have a 2016 1500 with a 3.6L v6 it currently has 140k miles. I have heard some people switch from 5w-20 to 5w-30 with high mileage vehicles. Any insight to this. Car has been reading 15-20psi when fully warmed up and idle and 35-50psi when between 1200-2000 RPM.

Been using PUP 5w30 since I dropped the oil it was shipped with.

It shouldnt hurt a thing. I switched from 5-20 in my 5.7 to 5-30 2 oil changes ago and its fine

Okay. I was wondering if this was common to switch from 5w-20 to 5w-30 at mileage? Or it doesn’t really matter?

I'll be switching as soon as my supply of 5W-20 runs out. Here are some more opinions...

5W30 OK in the Pentastar?

Previous owner said he ran 0W20 full syth since new. Didn't like the idea of running such thin oil, so my first change I used 5W20 High Mileage Synthetic Blend. Oil is on sale at NAPA and was thinking of getting some 5W30. Our other vehicles all run that grade and be nice to not have several...

If you got that many miles using what you're using then why change? Stick with whats working.

I've been using 0w20 since new, year round. At 177K engine still sounds happy.

2017 ram 1500...I was on an interesting oil journey when I bought my used ram. It would periodically tick on start up which got worse as time went by and required the intake gasket replace, fortunately on warranty. I was using bulk 5/20 at the oil change place. After the gaskets it still ticked from time to time on start up. Changed to 5/20 synthetic which lessened the occurrence but didn't eliminate it. I changed to synthetic 5/30 with Lubeguard Biotech additive which has pretty much eliminated the issue. I was reluctant to go to a heavier oil as I live in central b.c. where winter temps can range -20 to -40 but there has been no noticeable issue other than a noticeable improvement in operation particularly on highway and no tick. I highly recommend the Lubeguard which makes a noticeable difference....unfortunately in Canada it's about 30 bucks cdn but I don't drive much and only do 2 oil changes a year so it's doable.

I switched from PUP 5W20 to PUP 5W30 last year or the year before.

The temperatures here are anywhere from -30⁰F to 100⁰F+.

I've not experienced any problems starting in colder weather and the oil pressure is now about 30 PSI at idle and 50+ PSI on the highway. Up about 4 or 5 PSI.

My '21 Warlock only has 44K miles and I've been using LubeGard Biotech every winter since about the second year of ownership.

Last summer I bought 5 bottles of LubeGard and now use it with every oil change, summer and winter.

Check out the LubeGard thread and decide for yourself.

Did Lubegard Biotech kill your hemi tick??

So we have had a couple guys running biotech so we should start seeing some results, and hopefully this thread will encourage people with hemi tick to try other lubrication strategies. For those that follow, Lubegard Biotech is similar science to Redline, and as we have seen it can be an...
