03 trailblazer, 5w30 oil, 1 ticking lifer at cold start, 12 degrees or so. Miracle oil?


#1

What is your experience and recommendation? Oil change done 2 weeks ago. New air and gas filter in the mean time.


#2

I’ve had good luck with Rislone in the past. But I haven’t needed to use it in years.


#3

Thanks for that @ MikeInNH. Do you typically drain oil relative to additive?


#4

Substitute 1 quart of rislone for 1 quart of motor oil


#5

I like CD2 oil detergent for cleaning out. Use a 1000 miles or so before oil change. However, it may not help your situation if the engine is high mileage. If the ticking goes away in a minute or two, don’t worry. You can shorten it by using Mobil-1 0W30 oil. I find that this helps a lot on my old Chevy Tahoe. I only use that in the winter.

Ticking goes away once warmed up, 150k, Thinking an additive or a new oil change with catstrol high mileage or whatever the consensus bears. thanks @melott and @db4960


#7

If you’re dealing with 12F temps, I’d be using full synthetic. Are you?


#8

No I do not use Full synthetic @texases Never felt the need to, as regular has always served me fine, but it may be now is the time to look at the option.


#9

Exactly what db4690 said.

Drain…then replace one quart of oil with Rislone. It actually says that on the bottle.


#10

Purchase a bottle of Seafoam engine treatment and pour it into the oil.

If there’s a lifter stuck the stoddard solvent in the Seafoam will free it up. If the lifter keeps making noise then it’s a mechanical problem.

Yes, but the mechanical problem is part of normal aging, like an arthritic joint. If the ticking goes away on warming, it is not a serious problem. It is often due to oil starvation in cold weather. The lifter will get pumped up again faster if you use full synthetic 0w30.

Self Healing almost, I had some sea foam and decided to add it to the tank as gas mileage seemed poor, it was because of the cold I imagine, had a couple hours of freeway driving, then ater a low of 2 below no more noise!
