Hey everyone, this is the first time I'm doing oil change on my used 2017 Challenger RT manual. I got it with 5000miles and now it is almost 8000miles. I just want to get it done and let the dealer do their multipoint inspection. I ordered the oil change package from Mopar via phone and the guy recommended synthetic blend rather than fully synthetic(that I use with my Durango). I just want to make sure from the experts here on our beloved forum that it is ok to put synthetic blend on our beloved Challenger especially the RT's.

The 5.7L (345ci) engines leave the factory with Synthetic Blend. And, the monthly Vehicle Health Report that I receive from UConnect for our Durango R/T changed their recommendation from conventional to synthetic blend last summer.

Like you, I choose to run Pennzoil Platinum Full Synthetic in my Durango. (I run Pennzoil Ultra Platinum in my Challenger SRT 392.) I can't imagine that a "better" oil would cause a problem.

HOWEVER ... A year or so ago, I kind of, sort of, remember that someone quoted a response from @DodgeCares suggesting that they use a Synthetic Blend instead of Full Synthetic in their 345ci/5.7L Hemi. Dang memory really is the first thing to go.

Thanks a lot. I guess I'll go for synthetic blend because he already charged me for 3 oil changes synthetic blend for $108. Not bad. I call the same Mopar guy for my extended warranties and oil changes for my Durango and Fiat Spider(which I traded for the Challenger). I was just surprised he gave me a synthetic blend for my challenger and not full synthetic.

I'm pretty sure the Dodge engineers are smarter than me. (Most people are!!). And, if the engineers say that the 345ci/5.7L Hemi will be just fine with Synthetic Blend engine oil, then who am I to argue.

Still ..... I've used full synthetic oils in all of my vehicles since the early '90s. For me ... using the "best" (full synthetic) is cheap insurance. Especially when/if you catch it on sale.
