Ok so about 2 weeks ago i switched over to a mobil 1 synthetic blend, and now when i start my rig up she ticks for a good solid minute... never did this before with regular oil, i'm concerned that this is in someway gonna mess up my truck... does anybody else rig tick like this... i mean sometimes i'll go to the store after it warms up and no tick and come out about 20 minutes later and its ticking on startup again... on an 80 degree day so i know its not cooling down that incredibly fast!!! gimme your thoughts am i just paranoid or is there something else wrong in this case?

My Completely non professional, and un educated oppinion.... Its Chevy tick... Every Chevy I have had... and all of my friends have done it; and I have run Mobile 1 in all of mine except for one of them. Dunno what causes it, but I would consider it normal... Unfortunately.

My '01 4.8 will tick/nock in the winter when it gets down to the 30's or below. Lasts for about 30 seconds. If I leave it for a few days in the summer, it will also tick/knock when I firs start it up. None of this ever happened til last winter. Still runs like a bear!!

It is the pistons guys...I think chevy uses forged pistons and they take a little bit to warm up

I'd say it's more likely the Mobil1 tick. Switch to Pennzoil Platinum and the tick will leave. I had the tick when I used Mobil1 now I use Penn Platinum and no more tick.

thanks for the opinion guys... i know that it is definately the chevy tick just lately i don't know if i'm paranoid since i changed oils but it has definately gotten worse ... but thanks for the comments i think next oil change i'm gonna go with the penn. platinum and see how it goes!!!

 

thanks, :D steve

Talk like that could get an oil flame war started. :shakehead:

An a trick an old GM mechanic taught my now 89 year old Dad and that I still use is this: about every other oil change I add a half quart of transmission fluid (ATF) to the crank case of my vehicles and leave it in there for 100 to 200 miles. It is highly detergent and cleans the engine thoroughly, including gunk deposits. This is particularly good for quieting noisy valves. I then change the oil and filter and have very good running engines. This quieted my 2002 Suburban's 5.7 down and I have also used it on everything from Fords to Mercedes.

The chevy piston slap just means the parts are forged and machined to tight tolerances. The pistons have to warm up to fill the cylinder. synthetic oil is very thin and causes less resistance inside the engine. The dino oil may very well have dampened the sound of that tick.

thanks, i guess what I'm really asking is.. is this gonna hurt my engine down the road now that it's louder and lasts longer than when i had regular dino oil?

Short skirts=piston slap. I have never personally seen any PROOF that the slap causes damage, just some embarrasment.

I haven't done my 1st oil change in my truck yet, but plan on switching to a full synthetic (probably whatever is on sale at the time) so I'll have to wait and see if it happens to mine.

 

I do recall that when I was a Ford owner (previous life) the 5.4L Titan Engines had a terrible piston slap. Some sounded like a diesel when they started up on a cold morning! The GM's certainly can't be that bad!

Hey nothing against Mobil 1, I once used it exclusively but when Penn Plat. came out I gave it a shot and noticed no more tick. Besides the UOA's on Penn Plat are great!

I have used Mobil 1 in every vehicle,tractor,lawnmower, air compresser & engine i have owned since 1973. Never a noise caused,associated or caused by Mobil 1. Look elsewear for your noise.

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
