bring back the 3800 ..better tougher engine

I own a 212 Buick lacrosse, engine purrs like a kitten , quiet smooth, powerful. I use Walmart oil, 5/30 does not burn oil, change engine oil 4k Transmission oil every 30k, love my ride.

New cars haven't become less reliable. New drivers have become more negligent when the cars have become more reliant on tentative owners. 5K mile oil change. NO EXCEPTIONS! I have a Toyota Rav4 and even with all its reliability reputation every 6 months it gets an oil change. I don't put a crazy amount of miles on it so I prefer going by time instead doing them during the shoulder seasons (October & April) before the extreme seasons of Summer and Winter so it has a fresh batch of full synthetic for the hot and cold months. And don't cheap out on the oil. Mobil1, Valvoline SynPower, Castrol Edge, Pennzoil Ultra Platinum, Royal Purple, and Liqui Molly all are excellent options.

a thought my father told me many moons ago" Oil is Cheap, engines are expensive. change your dam oil"

Timing chain failure is because of the CRAPPY PCV SYSTEM! the passenger side PCV valve gets blocked

3000 mile oil changes on mine with 230,000 miles on it driving in NYC!!!!!!

I like the GM 3.6 liter strong, efficient, fast good on fuel and racy if need be, love it, in my Acadia Denali 2019. I ensure my oil is changed Every three thousand miles always

And use dexos oil. Dont even think of conventional oil. Ive seen some fleet impalas over 300k miles. Never a problem with the engine with dexos. Its the conventional oil that vapor off at lower temps leaving crud behind. That cheap oil change will eventually cost you

2016 impala 3.6 244000 mile driven bout 100 miles each way 3days a week maintenance myself for my wife oil changes every 5000 witn thr rite oil never burns any an no problems at all with timing great engine dextros approved oil .

The GM oil life monitor has always been worthless. It's designed to keep cost of ownership during the warranty period low. GM also gets energy credits for the reduction of waste oil.

I have one of these engines in my Pontiac G8. I change the oil every 3k miles and have never had an issue. Yet.

The best video I've seen in a long time. Thank you!

2010 Acadia 3.6 162,000 and counting. Does not use any oil between changes. Change the oil regularly with 5/30 synthetic, Kirkland brand, going to up my frequency after seeing this vid and reading some comets. Just cleaned the intake manifold with seafoam, replaced #5 coil pack(one on the back driver side) enlarged the PCV holes, and will next weekend change the spark plugs, intake manifold gasket and valve cover gaskets. Back Valve cover gasket has the upgraded cover to restrict blow by to the intake manifold through the PVC. Have ordered a small catch can to help keep oil/contaminants away from the intake manifold and valves. Starts and runs good. 17 to 24 MPG. Love the auto start and heated seats, Very clean quiet and so far reliable SUV. Oh and I can easily tow my 3,000 LB boat to the lake. I do worry able the timing chain, and the transmission but so far okay. Oh, also changed my front A-arm and ball joints at about 150,000.

We just bought a good used Buick Rendevous with the 3.6 engine. It has 90K and is a strong runner! I've always been a fan of engines with timing chains. They are very durable and less worry than belt equipped. We've also owned GM's 2.2 liter Echo Tech with 300k on the engine. The same issues with oil apply to it also. Change the oil at 3000 miles! Thank-you Joe for shedding light on the care of these engineering marvels!

Thank you Joe that's some invaluable information good to know.

2009 Holden SV6 (ly7) with 310,000 kms and still doesn’t burn oil.

My 2016 Chevy Colorado has the 3.6 VVT with direct injection. 305 hp stock and with a little tuning you can get around 325. My oil life monitor hits 10% around 3500 miles.

My 2012 Acadia has 152,000 miles on it with semi synthetic oil every 5000 miles. Works fine, although sometimes when cold, the first start of the day makes a loud rattle that lasts for less than a second. I think it’s the chain. A lot of the miles were highway. It still has the original brake shoes and rotors with 5 and 8 left on the shoes. Replaced the water pump at 120,000. Last week put KYB shocks and struts for 2400.00. Blower motor replaced 2 yrs ago. I’m glad it took care of it and when I see car prices today, I’m even more glad.

2014 Chevy Impala 2LT 3.6 I change the oil every 3k every since I first got it 💯😎

Great information! I am looking at a 2020 GMC Canyon with this 3.6L engine, that I knew nothing about until now. I am quite familiar with the 4.3L thing called an engine that I have had in 2 Chevy S10's. So I assume this 3.6L is the replacement. AND I was shocked when you said that the computer will tell you to change your oil at 12k miles!!! Wow! As a daughter of a mechanic, I would not dare go past 3500-4K miles between changes. Again Thank you for such a informative video!-Peggy Scott Edwards of Scott Motor Co Richmond Va. :)
