to avoid the dreaded yet infamous Dodge Ram engine tick, you should use a higher octane even though it doesn't call for it.
can someone tell me if this is true
You may still not avoid it but those 5.7s love 87 or 89. Important tip is don’t let that motor idle for loads of time. Keep the oil flowing cause that’s part of the problem. When the newer Hemis sit and idle for long periods of time the top loses lubrication. Even with the tick my high school buddy has a 5.7 that’s gone 200k mi and the motor runs great still. Yes it’s annoying no doubt but most 5.7s I’ve seen with the tick still run fine. I’ve only experienced a handful that actually gave out with the tick. My dads 17 rebel started ticking only when idling. He was also using 85 which is not the best thing to do. Once he started using 89 cause he doesn’t have 87 where he lives, tick went away. Keep up with regular oil changes as well. That’s about all you can do.
I don't see how a higher octane would work for you. You would only need a higher octane for engine pinging. At your model year even if you had pinging the computer should be able to handle the problem.
@jpparisio the HEMI tick comes from using to low of an octane and a high concentration of ethanol. It doesn’t lubricate the injectors correctly witch causes a tick noise.. they also have lifter problem due to a redesign. That’s why you can’t idle the 5.7s or 6.4s for long periods of time.
Interesting something new learned every day.
Any ticking usually means the timing is over advanced. Do a deep scan to see that the ignition is advancing properly.
