Looking at possibly buying a new 2023 Silverado WT 4x4 with the 8L90 and 2.7 Turbo Max, Crew Cab Standard box. Discounts are getting pretty good as inventory of trucks are piling up. Have the 8L90 transmission issues been sorted for the 2023 model year or are these transmissions still...

Does a 2023 Silverado WT 4x4 2.7 turbo, without a locking rear differential use traction control to apply the brakes to the spinning wheel to act as a limited slip? I am looking at possibly buying the above vehicle and am used to limited slip in my other vehicles, will the newer tech of...

Probably a stupid question… but why does HPL no VII 10w-30 exist when the 5w-30 no VII already doesn’t have Viscosity Index Improvers? also the case with the 5w-20 and the 10w-20?

Should I use HPL differential life 75w-90 w/limited slip additive for all my diffs or should I call them and order some without the limited slip additive for the ones that are not limited slip? referring to cars in my sig.

Did my first oil change on my new to me 2020 Mazda CX5 Grand Touring. 2.5 non-turbo. Manual and websites say 4.8 qts. Why did it take 5.5 qts. to bring the oil to the full mark on the dipstick? I used ramps, so the front up on an incline. While the oil and filter was draining I jacked up the...

Do the higher percentage of esters and PAO's found in higher end oils shorten the life of internal plastic engine components, such as timing chain guides, plastic valve covers, oil pans, seals gaskets etc.? I remember having a plastic funnel I used for drain oil that got brittle and cracked...

Thinking about using Ravenol products in my `18 4Runner TRD Off Road. Ravenol WS in the trans. Ravenol 75w in the transfer case Ravenol 75w-85 in the front and rear diffs maybe even get the Ravenol DXG 5w-30 for the engine? kinda of expensive stuff, but cheaper than the crazy Toyota 75w in the...

2020 Mazda CX-5, 2.5 Skyactive G (non turbo). Looking at using the oversize 7317 filter in place of 6607, any clearance issues? or functional issues? I see many run the Mazda filter and won't stray from OEM. Would like to do this due to already having the longer filter on hand for my Honda's...

I am an Amsoil Signature Series user in the vehicles I care most about. However, the engines of some exhibit piston slap until fully warmed up, especially during the colder climate. Reading through the reviews (mostly on Amazon) for Schaeffer's oil, almost all reviews rave about the engine being...

With all the good talk about HPL, I am looking at using their 75w-90 gear lube in the differentials of my `18 4Runner, `16 Suburban and `97 Dodge Ram. All 4WD, so 6 axles in total. Anyone have any experience with the gear oil they would like to share that makes it above and beyond the Amsoil...

Wondering what shifting characteristic differences there would be running Amsoil Sig. Series Fuel Efficient vs. GM approved/Licensed Dexron VI? Seems like GM tech's and engineers are really against running a multi-vehicle, non-licensed fluid. Application 6L80 for: - `16 Suburban - `12 Corvette...

On my `16 Chevy Suburban with the 6 speed and 5.3 L, I just did the change to the lower temp. thermostat as per TSB 21-NA-199 which lowers the temp 26 degrees F or 20 C. New full open temp. is 158F or 70C. https://static.nhtsa.gov/odi/tsbs/2021/MC-10207911-9999.pdf I wasn't having any issues...

Received from Rock Auto today: GATES K070701 made in China This was sent as a warranty replacement, because the one I received (from RA) and installed about 4 months ago developed a crack width wise on the backside of the belt. I wonder if the one from 4 months ago is from China also. I guess...

Looking for oil preference for this 12.5 Kohler Command from 1993 in a John Deere 38" garden tractor. I know that the manual calls for 10w-30 2 qts. for the temperatures of which I will be operating and a spin on filter. I have various 10w-30's. Does this engine care? Is it okay running Amsoil...

Is there a tool to quickly clean up corrosion on a aluminum wheel at the valve stem hole? This is my winter set of wheels for an `06 Honda Odyssey EXL. This is to fix a slow/med leak, I am not really concerned about how it looks. The salt/brine has done a number on these wheels and I just want...

Why is it that so many cars call for 0w-20 and many for 0w-40, but 0w-30 is almost unheard of. I know 0w-30 is available by some oil manufactures, but almost unheard of as recommended for a main recommendation? They chose 5w-30 instead. Seems like 0w-30 would be the new go to oil for the best...

Comparing (3) AMSOIL 10w-30 for Outdoor Power Equipment Pro and Cons of: - 10w-30 ASE (Small Engine oil) - 10w-30 ATM (Sig. Series) - 10w-30 ZRT (Z-Rod) I am currently using ASE, however, none of the equipment has a wet clutch. I understand that ASE lacks some kind of friction additive? so...

Amsoil raised the price of their 5w and 10w Signature Series oils to match the price of their 0w Signature Series offerings. It used to be slightly more for the 0w offerings. I was under the understanding that some of the ingredients required for the 0w oils were more expensive. I guess things...

So the oil and filter in my `16 Suburban is now 1 week over a year old. I received an e-mail of my monthly diagnostic report and YES my OnStar diagnostic report said immediate action needed as my OLM went to --. However the driver information center in the car is still at 65% with no alert to...

In my one grease gun I have Valvoline Syn. grease w/moly go firm/dry on me. It doesn't want to pump nicely from the grease gun and the grease seems dry. I know some oil has separated and leaked out. This tube is about 4 years old. It happen to the previous tube of the same grease as well...
