Ohanacreek Posted January 8, 2014 Share Posted January 8, 2014 When I noticed that it takes 9qts (8.5 but I don't know anywhere you can buy half quarts) of $12qt full synthetic, I shat a unicorn. I think that is what everyone is pissed about. Why a weight you can only get in full synth when 5w-20 is available far cheaper and unless you live north of the US/Canada border will likely never need?

legierk Posted January 12, 2014 Share Posted January 12, 2014 I've been buying the Valvoline, because, as stated, it's not licensed and therefore way cheaper. If I ever see Wal-Mart brand 0W-20, I will buy it, depending on price. Haven't seen it yet down here in Texas. Link to comment Share on other sites More sharing options...
Ohanacreek Posted January 13, 2014 Share Posted January 13, 2014 People really its oil. Just buy what's recommended and deal with it. You have trucks that have breaking rear windows, rear diff howling, seats that dance, a truck that vibrates like an old bias ply 1/2 million mile heap, trans that still shift as stupid as they did in 2007, options that blatantly don't work and now you have to complain about oil viscosity.... yeesh. Sent from my SGH-I747M using Tapatalk I have none of the problems, the trans shifted funny with 275/70-18's but with 265/65-18s back on it, it shifts so smooth I barely notice, stays right around 2200rpm unless I push the go pedal harder than I normally need. With a trailer I put it in tow mode and again fairly smooth shifts (it is firming the shifts to tow) With the factory size tires it gets 23 Hwy and I can't tell when it swaps to V4 unless I look at the dash. 275/70's and it cuts mileage to 15mpg. AFM can't handle oversized tires with a 3.08 Ratio Link to comment Share on other sites More sharing options...
Gone Again Posted January 28, 2014 Share Posted January 28, 2014 Advanced Oiling System The oiling system on the engines incorporates a new variable displacement two-stage vane-type oil pump that enables more efficient oil delivery, based on operating conditions. Its dual-pressure control enables operation at a very efficient oil pressure at lower RPM, and then delivers higher pressure at higher engine speeds. An oil control solenoid valve, controlled by the ECM, mounted to the oil pump provides two-stage functionality. The oil pump is mounted on the front of the engine block and driven directly by the crankshaft sprocket. An oil passage at camshaft bearing location permits oil flow into the center of the camshaft. Oil enters the camshaft, exiting at the front and into the camshaft position (CMP) actuator solenoid valve. The CMP valve spool position is controlled by the ECM and CMP magnet. When commanded by the ECM, the CMP magnet repositions the CMP actuator solenoid valve spool directing pressurized oil into the CMP actuator to control valve timing. Oil pressure gauge needle oscillation will occur due to the two-stage oil pump self-test. The ECM will perform a functionality test of the two-stage oil pump after a cold soak, when the engine is first started and the vehicle is driven. This functionality test will occur three times in a short time span and can be observed on the oil pressure gauge as a brief increase (spike) in the oil pressure gauge needle. Additionally, at 3,500 RPM or greater, the two-stage oil pump switches over to high stage and the oil pressure gauge needle will move to the high position. New Fluids Engine oils meeting the requirements of the vehicle will have the dexos 1 certification mark on the container. SAE 5W-30 is the required viscosity grade for the 4.3L engine and SAE 0W-20 is the required viscosity grade for the 5.3L and 6.2L engines After reading this, the oil required by GM should be used.

nomadicdogg Posted January 29, 2014 Share Posted January 29, 2014 Has anyone gone full synthetic with mobil 1 5w-30 like the camaro's are running? thoughts from gm on that? Link to comment Share on other sites More sharing options...

AFM can't handle oversized tires with a 3.08 Ratio You also have to take in account that the 275/70's are a 10ply tire. Mine are about 14 lbs each heavier then the stock. Add the 3.08 gears on that and yes your probably going to feel a difference. I have the 3.42 rear and have not felt any difference, other then braking distance.

Black02Silverado Posted February 10, 2014 Share Posted February 10, 2014 Has anyone gone full synthetic with mobil 1 5w-30 like the camaro's are running? thoughts from gm on that? Why would you want to go away from what GM recommends? Especially with an entirely new oil system design. Could you run 5w-30, probably but it also might cause some issues. I guess some out there will use it and then we will find out when they post either good or bad. I would just stick to 0w-20. I have ran a 5w-20 in my old 2002 5.3 and it worked just as well as 5w-30 according to my UOA's. Link to comment Share on other sites More sharing options...

Tapatalk via Moto X The BFGs are all 10ply no matter what size. I didn't put factory tires back on just factory size. However, I have had the truck at the tire shop they've put 6 sets on trying to get them to valence. From 65mph on they VIBRATE with varying results from each set/combination. Love the capabilities of the tires( I was able to get around with no issues in the ice feat we had down here week back) but REALLY can't take the out of balance ride of them over 70mph.

And because I would rather go full synthetic than a blend like the dexos 0w 20, its not even the weight issue its more synthetic vs blend for me Link to comment Share on other sites More sharing options...
Black02Silverado Posted February 10, 2014 Share Posted February 10, 2014 You can get a good quality Dexos oil at Walmart in a 5-Gallon jug for less than 20 bucks! WHY IN THE WORLD WOULD YOU NOT BUY THE DEXOS LABEL FOR LESS THAN TWENTY BUCKS? Heck, if I could get 5 gallons of dexos1 oil for under $20, I would be buying all that I could and reselling it and make a killing. It has been a long time since I have seen a quart of oil for $1.00 at a regular price and not something on clearance. Link to comment Share on other sites More sharing options...

That makes sense. You can run a full synthetic, but it will only save you money if you extend your drains. Otherwise a dexos1 5w-30 blend will serve just as well. To really tell if you are getting your money worth, a used oil analysis is the way to go. Then you know exactly how far you can extend your oil changes. The OLM is a good guide but I have seen some that use it and had the oil tested and the oil was shot and not protecting like it should, the oil went way past the mileage of protection.

I am getting the 6.2.. the same as in my camaro which runs the 5w-30 FULL synthetic vs the 0w-20 sythetic blend dexos that the trucks are requiring.. I wasnt really questioning the weight as I know they did that for MPG alone, I am more questioning why go to a blend vs a full synthetic? Link to comment Share on other sites More sharing options...
nomadicdogg Posted February 10, 2014 Share Posted February 10, 2014 after doing some quick research... Mobile1 has a dexos1 approved 0w-20 FULL synthetic oil vs blend. This is what I plan to run wal mart has 5 quart bottles for $25.. not a bad price for full synthetic. Ac delco dexos is a blend.. id rather go full synthetic.http://www.mobiloil.com/USA-English/MotorOil/Oils/Mobil_1_0W-20.aspx Link to comment Share on other sites More sharing options...

Im going with full... Link to comment Share on other sites More sharing options...
