Do SN+ oils meet Dexos 1 criteria?

Just bought a 2017 Buick Envision. Nice car, great deal. Surprisingly made in China with 98% Chinese parts content. Engineered and designed in Detroit. Here's my question. The owners manual plainly states to use Dexos 1 5w30 with AC Delco Syn Blend recommended.On the engine fill cap it states...

Just out of curiosity, I wonder who sells the most motor oil. I would guess; 1) Penz 2) Exxon/Mobil 3) Valvoline 4) BP/Castrol 5) Store brands (Super Tech, AutoZone, etc) 6) Quaker State

so i just bought a brand new cadillac srx. this is going to be our "travel the country" in our retirement car. we get free oil changes for 50k from our caddy dealer. they use dexos 5w30 syn blend. so who makes this stuff? Thanks, guys.

I've got an 06 Vette with less than 50k miles. Still have original Dex Cool in there. Looks fine, tests fine. Any reason to change it?

I am absolutely perplexed. A substantial amount of water showed up in the back passenger side of my Malibu. Carpeting is absolutely drenched. Wetness starts under the front passenger seat and goes backwards. I can't detect any leaks around the door molding or windows. Nothing has been spilled or...

For whatever it's worth, the WM House Brand Full Syn is now GM4718m compliant. (Meets Corvette Specs). This is more than can be said for Castrol Syntec, Mobil Super Syn. Just had the oil changed on my Vette for $37.70 at Walmart including an AC/Delco filter and 6 qts of SuperTech.

Would use of a high mileage oil help cure a slight upper pan gasket leak on a 2006 Buick LuCerne with the Northstar V8 engine? 83k on the ticker.

My daughter is considering the purchase of a brand new sonata with the 2.4 litre engine. I saw on their website that they recommend a 7500 mile OCI, but it did not specify oil type; ie dino, syn. Anyone familiar with this vehicle's requirements? Anything unusual maintenance wise required? She...

I didn't feel like crawling around on the garage floor to change my own oil and I had a $12 off coupon for the JL, so I took my 09 Malibu in for one of their 15 minute Signature service Oil changes, expecting to get PZ 5w30. Instead they were using Formula Shell in bulk. Nothing wrong with...

I'm running QS Ultimate Durability (full syn) in my 06 LuCerne with the 4.6L Northstar Engine. Oil Has been in there 16 months, OLM still showing 45%. We don't put alot of miles on the car, but the vast majority are hwy. Doesn't use a drop of oil, 72k on the ticker. Why dump it before the OLM...

My Buick with the 4.6L Northstar has 72k on the clock with original coolant. Owners manual says 5 years or 150k whichever comes first. Current coolant tests fine and appears clean. Do you think I should change it out? My local Firestone Store is running a special on it. They say they use Peak...

I spilled some gas in the trunk and got the carpet wet. I've taken the carpet put to air it out, but it still stinks. So does the trunk. My wife won't drive the car (and I don't blame her). Any suggestions?

Had a great experience here at my local Walmart. I cut out an ad for a $12.95 oil change a local stealership was running and took it to the Tire and Lube express. They matched it no questions asked. They used their bulk oil 5w30 Quaker State and their standrd Fram Extra Guard filter. In and out...

A set of FR 710's came as Original Equipment on my '09 Malibu. 215-55-17. Smooth, quiet tire. In 14,000 miles I've had FOUR flats, all from picking up a nail or other road trash. Traveling the same routes I've had zero on my other cars; one has Continental Contac AS, the other Goodyear Eagles...

This is my first post on this particular forum, so pls cut me some slack if this topic has been previously beat into the ground. My local trans shop (reputable)is running a special on a "premium flush". They say they use multi purpose trans fluid and dump an additive in to convert it over to...

Am thinking about putting a set of the Firestone Firehawk Wide Ovals with Runflat on my '06 Corvette. Anyone have any experience, pro or con, with these? They seem to be a good value relative to the Eagles that came as Original Equipment.

Just did my patriotic duty and bought American; new Malibu with the 2.4L Ecotech engine. Was surprised to see GM went to a cartridge type filter, as opposed to their traditional can design. Seems as tho the OLM is taking me out to a 6,000 mile OCI for a 50/50 combo of city / hwy driving. Are...

Just got an Email from Mobil 1 apologizing for the shortage of product. They blamed it on the effects of Hurricane Ike on their raw materials supplier. Came along with a $10 rebate coupon for a future purchase, redeemable between April 1 and August 31. So that's why the shelves have been bare at...

They just re-paved my subdivision with a fresh load of blacktop. Too much of it has found it's way onto my White Corvette. It doesn't come off with soap and water, nor does Meg's detailer spray and wipe put a dent in it. AARGH ! Suggestions?
