As far as my good, better and best picks:
Super tech fs, Magnatec, M1 EP.
Super tech fs, Magnatec, M1 EP.
We rented an Opel when we went to Ireland in 2018. I forget what model, I'll have to dig up the pics, but it was similar to a Buick here in the states. Was a nice car.I thought the latest on LSPI in GMs are to use a low calcium oil that meets/exceeds Dexos 1 Gen 2...GM uses a Mobil product that is full synthetic (likely similar to Mobil Super Full Synthetic)...I'd like to read more as the GF's 2013 Malibu 2.0T has been fed Mobil 1 5W30 for most of it's life...
enjoy that Regal Sportback...wish Opel had remained with GM and that they still made the sportback, GS and TourX

Here's two (technically three) Pennzoil Platinum UOA's by Wix and Napa that show Pennzoil Platinum 5w-30 shearing into, or very close to 5w-20 range from the last year, first page of search results for "Pennzoil Platinum"Not really, or at least not documented. Blackstone (which are most of the UOA on this site) is incapable of properly measuring viscosity and is even more incapable of determining whether a deviation is due to mechanical shear or fuel dilution. Besides, whether an oil undergoes mechanical shear is highly dependent on the specific engine. SOPUS Products does not use cheap VII either.
My mistake thank you for the correction on the upper limit.Actually the upper limit for 20 grade is 9.29 cSt per SAE J300, and of course PP 5W-30 should work just as well as any other D1G2 approved oil because it has passed all of the same tests. It's factory fill in my Jeep Cherokee 2.0L turbo and it's what I use with 100% confidence.
Neither one tested for fuel, correct? Especially on the DI engine I'm still not buying that it's mechanical shear.Here's two (technically three) Pennzoil Platinum UOA's by Wix and Napa that show Pennzoil Platinum 5w-30 shearing into, or very close to 5w-20 range from the last year, first page of search results for "Pennzoil Platinum"

Looks like you're correct on the lack of fuel dilution testing for those tests.Neither one tested for fuel, correct? Especially on the DI engine I'm still not buying that it's mechanical shear.
Lots of people like to blame it on shear but there's precious few that are confirmed. The one with the Ford where I participated is full of yapping but like I mentioned in the thread, no proof of what happened at all.
People who know Buicks know they are a fantastic value.Like most people say here, just use a 5w-30 Dexos oil and it’ll be fine.
The thing to watch out for is that GM issued a TSB on using oil filters with too low of a by-pass pressure setting. It should be something above 20 psi. Some aftermarket ones are set too low. The good news is that the OEM AC filter is fine and the recommended Fram and Wix/Napa filters have the correct bypass pressure. I just slap a Fram XG12060 on my Regal and call it a day.
I’ve had my TourX for almost two years and it’s been totally reliable. Possibly the best car I’ve ever owned.
https://www.mobil.com/en/lubricants/for-personal-vehicles/our-products/products/mobil-1-5w-20/Hi All, Recently purchased a 2018 Buick Regal Sportback with the turbo 2.0 engine.
Never owned a tubo before or a 4 cylinder either. Maunal calls for Dexos 5/20.
Curious if any brand is superior with a turbo engine
Thank
are you saying the AC Delco PF64 and the Fram Ultra are identical filters now???...Name brand dexos 5w30 and a Acdelco PF64 or equivelant (fram ultra). Nowhere does it read online or in GM's parts catalog to use 5w20.
I read that Opel is profitable under its new ownership...something GM couldn't accomplish for many years...I thought the latest on LSPI in GMs are to use a low calcium oil that meets/exceeds Dexos 1 Gen 2...GM uses a Mobil product that is full synthetic (likely similar to Mobil Super Full Synthetic)...I'd like to read more as the GF's 2013 Malibu 2.0T has been fed Mobil 1 5W30 for most of it's life...

the insignia has been constantly mocked and ridiculed on the other side of the ocean for the longest time.GM does have a habit of finally getting the car right and then ending production...
