That is what I am afraid of. Going to stay with the Mopar filter though.the special, like to use mobile 1,, about a quart every 1200 milesand that was back when it had around 70K,,, lifters rattled also,,, a good hi mileage oil is what I would use,, (ok,, I do use Castrol hi mileage10w30)
interesting that the leaks stopped whed you switched back....Theory is the additives help to 'swell' aging rubber seals (valve stem, crank, etc) that may be on the verge of seeping/leaking, or leaking already.
It's also usually a blended oil of dino/synth.
If you've run pure dino for the past 100K miles, switching to full synth is fine, but it's possible that after a few changes, you may develop an oil leak where there was none before, due to the cleaning nature of the full synth...
I attribute this to the leaks on both the LHS and the Trep in 2010. Once I went back to a high-mile (I like Valvoline red-jug) those gradually disappeared.
YMMV. I can only offer my own experience/opinion.
Well no, but if they do provide harshly negative feedback, some planning can begin.really,, if your analysis, comes back bad,, what can you do?? run out and buy a new car??
Sounds like a plan. I tell you what, I will send you a sample to Doctor Dodge Oil Analysis Inc. And you send back results that are bad and recommend I run right out and buy a Challenger 6.1. Oh, and mistakenly address it to Mrs Duds.really,, if your analysis, comes back bad,, what can you do?? run out and buy a new car??
