So, I'm reading this, and I'm confused. I thought the "Hemi tick" was from broken exhaust manifold bolts. Is this tick different? If so, what causes this one and what's the deal with Redline? Is it some special ingredient or addative? Finally, I see some use 5W30 and others use 5W20; do some Hemis require heavier oil or is that personal choice and does the heavier oil provide any advantage?
Thanks.
About 50/50 half are bolts and half are lifters.
Redline is esters which are dense and withstand heat and are polar by nature meaning the seek metal instead of run from it like regular hot oil, pao which is stable branched chain lubrication, high moly which cuts the coefficient of friction in half and creates a plate under high heat time and pressure, and has high zinc which is another thing that protects metal.
5w20 versus 5w30 is preference, I have had equal luck with both, but some others have not, they have had better luck with 5w30, which is why we call it hemi honey around here, that specific weight.
Long term use of redline has produced great low wear numbers as well proven by uoa's.
So hears the thing, many hemi's have had issues with cam and lifters and long term members seen this over and over and have followed science into this solution. But, if you don't have hemi tick you can simply move from your favorite 5w20 oil up to 5w30 and that will give you some extra protection. You can develop your own strategy by researching it, you may not opt for redline. As for me, this hemi will only get redline 5w30 and I had so much luck with it I can't imagine using anything else even if I switch cars. Until I seen it kill over 20 hemi ticks including my own, I wouldn't have believed it. Seams like every other week another postive story comes up. It surely isn't 100% at killing ticks, but pretty close. There is a slight risk if the engine has over 75k miles of noise getting worse before better.
You may want to read my oil filter thread in my sig, really good unbiased info there. You can also read the quiet hemi tick thread posted by h395.
let me ask you, do you have hemi tick?
