C8 z06 oil change on the cheap with oil analysis

[@HorsePowerObsessed]

Interesting results from Blackstone. Good job, Brandon!

[@lukewalker1051]

Well done Brandon. Nice explanation to Z06 DYI'ers. Will further say, you are a man of taste. Love the color and spec of your Z06 and you aren't throwing non-value added gratuitous mods at it unlike other youtube presenters. Glad to see your oil analysis is on the money. PS. On a special car with special engine like the LT6, I personally would change the oil at 3K intervals.

[@dbmracing2019]

I’m definitely doing mine every 3k miles

[@Brandonsgarages]

Thank you and I’m probably gonna change mine more frequently especially the trans filter after watching HPOs experience w his and the shifting. Will probably send some trans fluid for analysis to see what that looks like. Thanks for the comment !

[@lukewalker1051]

@@dbmracing2019 and if Brandon and others are looking for a reason for viscosity degradation at 6K miles....likely due to the RPM redline of the LT6. Reason this matters is, high reciprocating piston speed creates viscous shear contributing to viscosity breakdown in general and why race motors as an example require more frequent oil changes. Viscosity of course not only modulates oil flow and pressure in the engine but also regulates oil film thickness for adequate protection aka no metal on metal. So changing oil at less than 6K miles is less about contamination. I wasn't sure if this was Brandon's first oil change but break in oil has different properties as well conducive to cutting and bedding of mating parts and why important to get it out of the engine early including shedding of metal from mating parts at initial break in.

[@dbmracing2019]

Nice work Brandon! Good information! And good call for getting analysis at Blackstone! Going to do mine soon and send to Blackstone as well!

Looks like there’s no way to do an oil change without taking a bath in it with this car. Good DIY video Brandon. 👍

[@Brandonsgarages]

@@lewislgZ06 might be, but I’m messy lol

[@Steveleanr]

I did the oil analysis, very detailed, when I did the oil change. and it's inexpensive.

[@Brandonsgarages]

@@Steveleanr what did yours show? Similar ?

[@Brandonsgarages]

@@Steveleanr I’m gonna send some DCT fluid I think and see how that looks

[@Lawrence-pv3hg]

I have done 4 of them on my 2020 Denali 1500 with 3.0L over the last 52k miles. So far they show that I have no problems and can extend my oil changes. I originally got it because different dealers were giving times for oil changes. I got 20%, 10% and even 0% oil life. I have now consistently been doing them at 0% oil life or 7500 mi and still have over 2k of oil protection. This is with factory oil and filter, towing a car at least once, city and highway driving. I don’t exceed the 0% or 7500 miles owner manual says since it’s under warranty but Blackstone says oil is good for at least 9k mile. If you pay for the TBN add on, it tells you about how much protection is left in oil compared to new oil. This doesn’t mean you don’t need to check oil levels as that is what causes more engine failure. The shop that said 0% charges reminded me to check level regularly. As engine gets older you can develop leakage or burn it. Oil that last 9k miles does no good when it’s not in the engine.

[@vinnier6]

I felt like you were about to crack that oil filter cap

[@Brandonsgarages]

@@vinnier6 I was probably close

[@2020matrix8]

Great video Brandon!

[@NonstopBigVisc]

Why’d you remove and replace the oil filter first? I would have done that last (not sure if it makes a difference)

[@Brandonsgarages]

@@NonstopBigVisc according to the service bulletin it should be two drain plugs THEN oil filter. Good catch!

[@RudiWeber-dr5qc]

Hey Brandon, I see some throttle body on your table in the KZbin movie.Do you have the throttle bodies from Soler Performance on your Z06 and do you have any problem with CEL. Thanks

[@Brandonsgarages]

I do have them. No light but I do get a CEL on occasion from my cat delete piped which I delete. Comes on every 300-1000 miles. I’m happy w the TBs and the controller

[@RudiWeber-dr5qc]

Thank you for the fast response, I'm waiting here in the UAE on my Corvette C8 Z06 Performance. my intension is to do the Fabspeed Sportcats in combination with the Fabspeed Titanium exhaust, the Soler Performance Throttle Bodies and af course the Inventuri intake, I hope it's going to work fine together. Keep up the interesting videos.

[@Brandonsgarages]

@@RudiWeber-dr5qc that’s a great combo I’m sure you will love it! Plus some nice weight savings! I’m installing Corsa cat back next week suppose to save 31Lbs . Ur gonna save a ton of weight with that eventuri and TI exhaust

[@NYCz06]

Is there a gasket that has to be changed on the 15mm drain plug. Watched a bunch of different videos nobody mentions a gasket on the 15mm drain plug

[@Brandonsgarages]

@@NYCz06 no gasket on the 15mm one. The plastic 3/8 oil tank plug does have an o ring on it tho.

[@NYCz06]

@@Brandonsgarages I noticed a little oil on my bolt. Do you think it wasn’t properly torqued from factory

[@Brandonsgarages]

@@NYCz06 I noticed the same and even now I see some on my 3/8 plastic one just a little and on my 15mm plug . They are pretty meticulous on the oem assembly so I doubt it but anything is possible. I think thermal expansion of the different metals sometimes causes seepage that’s ever so slight. Just my thoughts cause mine also has some on it now just a tiny amount w me torquing it.

[@NYCz06]

@@Brandonsgarages think it’s anything to be concerned about? Mine was on the 15 mm plug. I check oil after every fill up so I don’t think I’m losing much

[@Brandonsgarages]

@@NYCz06 no I think it’s fine personally. I never see any actual drops on the ground

[@richarddobreny6664]

Why on earth did GM not use a metal plug instead of a plastic one? There’s an aftermarket opportunity there!

[@Brandonsgarages]

@@richarddobreny6664 not sure , maybe didn’t wanna risk stripping the oil tank? I dunno. Older generations had metal tank but I’ve noticed lots of manufacturers going polymer on oil pans, etc. maybe cost /heat/weight thing I am not sure.

Hello👋🏻

[@Brandonsgarages]

@@Cars-N-Jets hello sir!!!

[@redbird444]

Blackstone is good except for oil dilution as they don’t use gas chromatography for true accurate results.

[@Brandonsgarages]

@@redbird444 thanks for the info

[@Mykytys]

No matter what you thought about it, I think you put too much torque on the bolts anyway. The factory guideline values ​​are what ALWAYS must be followed.
