Engine Oil brand

Mobil 1 synthetic, since that's what the dealer uses.

I have more experience in maximum stress on engines than you can imagine. Hundreds of equipment sold in the land clearing ROW maintenance field. That run maximum RPMs 8-12 hours a day in extreme dusty conditions. I don’t just go by my experience. Being a Amsoil dealer, redline dealer among others we’ve tested for them for 40 years. We’ve never lost an engine due to oil. If you believe engines to day need less care today fine good luck. Turbos, cylinder deactivation, stop start technology suggests otherwise. So do the manufacturers.

Again, I follow GM’s recommendations, I already said that. I understand engines have changed, but so has oil. Not just Amsoil. Any modern oil meeting Dexos is going to be one of the best on the market, and better than anything was even 20 years ago. And as a fact, oil change intervals as a whole have actually been extended quite a bit over the years by the manufacturers for this reason. (This seems to come much to the chagrin of people here with a vested interest in selling oil.)

Advocating against people blindly wasting money, time and resources by dumping the FF after 1k, replacing it with the most expensive product on the market, and then dumping that early too is not advocating against proper maintenance. I am the only one here advocating for proper maintenance right out of the owner’s manual. I don’t even think Amsoil is Dexos, is it? Hmmm.

You have the right to use any quality 'full-synthetic' oil and oil filter of whatever brand you prefer. Be sure to change it at or before the interval indicated by your Oil Life Monitor. For me, that currently means Shell Rotella Gas Truck oil from WalMart and Wix XP oil filters. I don't use the AC Delco e-core oil filters--there have been too many horror stories of them breaking apart inside and ruining engines. I also like Pennzoil Platinum and Quaker State Ultimate Durability. GM's own Dexos oil is good, too. Mobil1 was top-rated back in the 90s but has since been surpassed in a lot of tests. I don't see the need to buy the more expensive/hard to get AMSoil/Royal Purple/Redline that are overkill for normal use, especially when one considers the questionable quality of the cylinder deactivation system parts (how many on here are on their 2nd or even 3rd set of AFM lifters?) built into our trucks. Not to mention that I'll bet I've added $1000 worth of oil in between oil changes on our 2009 Silverado, and that's at Wally World's discount pricing.

I have experience with Amsoil among others. I really don’t care what brand of synthetics people use. There’re all Jonny come lately in comparison. I have cars under warranty that I get done at the dealer. They use their own synthetic. My 29 year old blown stroked truck gets Amsoil yearly. It only gets driven 5K miles a year or less. I’ve had trucks that pulled heavy loads gas and diesel at near red line for hours on end on the stuff. Same with heavy eq up to 1000HP. Probably wouldn’t hurt to use cheap store brand as long as you change it often. I was a dealer (retired) and a fan boy[emoji14] I was with GM too. I’m still using Amsoil. Can’t say the same for new GM trucks. Don’t like Frankenstein V-8s.

Education is the key, You have to pay a fee to GM to be labeled Dexos approved no matter the oil manufacturer, Amsoil has surpassed all the minimum requirements but refuses to “pay to play” buy whatever you want but like Karnut mentioned previously, requirements have changed, sooner OCI’s rather than later are recommended. Good luck.

I understand completely the perceived “sham” of getting certified by these manufacturers. Though I don’t think that’s GM’s sole intention for creating the standard.

Frankly, I wasn’t even knocking Amsoil for choosing not to get certified. But when one wants to pound the table about what manufacturer’s recommend, at the same time singing virtues of an oil that they don’t...well, you see what I’m saying. I guess I’m too literal.

The specifications for Dexos2 certification and SAE SN-PLUS are identical. GM however will only license certain SAE Grades.

0W20-5W20 and 0W30-5W30 SAE grades. There is exactly ONE licensed 0W30 Dexos2. A Mobil 1 product. A handful of 5W20's. This segment is dominated by 0W20 and 5W30 oils. That said other than the viscosity requirement they are identical to any SAE SN-PLUS in base oil and additive package requirements.

This next part if funny. Dexos licensing requires 'no conventional' ingredients. Then okay's Semi -Synthetics which by very definition are in part convention Group 1 or Group 2 base stocks. Guess someone in legal missed this one.

Bingo! Being that GM owns the rights to “Dexos” Not only does GM require up front play to pay but GM gets a kickback from each and every oil manufacturer of Dexos labeled quart sold world wide.

Thanks for posting, They’ve been fighting for this exclusivity for years, GM along with each and every manufacturer out there hates competition and Amsoil is #1 on their list. They want exclusivity to all repairs and servicing so they can monopolize the industry which is one of the reasons for coming up with this Dexos BS, manipulating people into believing the Dexos is their brand and the engines are designed to work only with Dexos stamped oil LMFAO! Amsoil did their test and blew everyone out of the water. People can choose to believe whatever they chose but it’s best they educate themselves and stop being sheep.

Can't beat the price of this at Walmart. Less than $18 for 6 quarts and the more you buy, the more you save. Made by Chevron & Dexos approved. Good enough for me! I stocked up:

Additive companies develop licensed formulas that they offer to oil companies to re-license. It is inexpensive to re-license one of these formulas, and the majority of oil companies choose to do this to avoid the costs associated with testing their own formulas. This lowers the value of such engine oils because the same chemistry is being sold under many brand names.

If good enough it good enough for you, then buy on price alone because there is very little differentiation among dexos licensed brands. Its all made to a price point.

I only use ac Delco oil filters. If it was to break apart and destroy the engine would something like that be covered under warranty? I can’t see why it wouldn’t. Heck the dealership use that filter for oil changes.

I ordered a bunch of those too from Walmart along with the Havoline oil, Lol!! They sell multi packs and the more you buy, the more you save. Ended up paying something like $5 per filter!

Just adding more of a particular ingredient doesn't always make it "better". It can be like taking vitamin C... It's good, but your body can only process and make use of so much, so adding twice as much to your smoothie doesn't make it twice as good for you. Having additives and detergents is good... just adding more doesn't always mean that it will clean twice as much, or protect twice as much...

Go anywhere, and you will find people who are loyal to their brand, who has a 300k mile vehicle still running strong.

If you take care of it, change the oil and filter when you should with a quality oil and filter, you aren't gonna find that on average, the cars with Amsoil last 2x as long as Mobil1 cars... I would say that any correlation with longevity probably has more to do with how OCD the owner is with maintenance, and less to do with the label on the bottle of oil...

I get that Amsoil guys have a cult-like following with their brand of oil... They are usually evangelists about it... But I don't know that there are many long term credible studies that show that motors that use Amsoil, tend to last significantly longer than other top tier oils, based on the choice of oil alone.

If there are, post the links, I would love to read them.
