5W20 Under 45 Degrees F. ?
Say you live in the PNW and your air temps have a limited winter range (20 degrees F. to 45 degrees F ) for suburban driving conditions. For a Kia Seltos 2.0L non - turbo MPI engine - do you just stay with a D1/Gen 3 5W30 or drop down to the same in a 5W20 (or even a 0W20 ?) for 6 months / 4K...

M1 5W30 vs Valvoline Advanced Wear Protection ?
While M1 5W30 is a fine oil , I like the fact that Valvoline Advanced 5W30 has a large amount of moly (approx. 2.5X to 3X more than M1 ) but then I started thinking : “Just how much moly is enough over a 4K mile OCI” ? Is it possible that although M1 shows a lower amount of moly in a VOA versus...

M1 5W30 EP D1 / Gen 3 Users ?
I usually run 5W30 non - extended performance 5W30 synthetic oils (Valvoline Advanced , Quaker State Full Synthetic, etc. ) in my '17 Sonata GDI 2.4L non - turbo engine along with a Fram Ultra oil filter. My OCI's accordingly have been 4K ~ 5K miles / 6 months max . In the same vehicle I thought...

Reducing Likelihood of Sludge & Varnish ?
Using modern synthetic oils rated for your vehicle , using a good oil filter , regularly checking PCV valve for proper operation and OCI's of less than 5K miles or 12 months max - this is all I can think of to reduce the likelihood of sludge & varnish ... Your thoughts and experiences ?

Cross Country Trip : 5W20 or 5W30 Synthetic ?
Seltos oil cap says 5W20 (5W30 , 10W30 are also approved in OM) . I have been using 5W30 synthetic oils for mostly severe large city suburban driving but will be taking a cross country trip this summer . For a cross country interstate run would you stay with 5W30 or drop down in weight to 5W20...

Your Max OCI (in months) With Synthetic Oils ?
Providing you do not reach your preferred OCI mileage first (i.e. 5K , 7.5K , etc.) what is the max length of time (in months) you establish as part of your OCI routine with synthetic oils ? For most of us - it's usually a mix of highway and suburban driving with the occasional stop & go city...

Euro A3/B4 Synthetics in Asian GDI Engines ?
Some people believe stepping up to a 0w40 or 5W40 Euro A3/B4 Synthetic oil is doing them good in a Hyundai , Kia , etc. GDI engine versus the 5W30 (SP , G-6 , D1G3) rated oil shown in the owner's manual . *The concern I would have - even with M1 0W40FS (closest rating to a 5W30) is the ash...

Best Readily Available 5W30 Synthetic for GDI Engines ?
By now you would think there would be enough research , real life examinations , etc. to determine best readily available 5W30 synthetic oils to combat intake valve deposits which are still an issue with GDI engines . My Hyundai 2017 2.4L (non - turbo) GDI engine recommends 5W20 on the oil cap...

M1 0W40 In Place Of 5W30 ?
My Hyundai 2017 2.4 GDI OM states I can use 5W20 , 5W30 or 10W30 in this Theta II engine ... I have read that M1 0W40 is really at the thicker end of a 30W oil so it appears I can safely run this oil ? The M1 0W40 generally gets good reviews and curious what benefits I would see using this 0W40...

Next New Oil You Will Try ?
What is the next new oil you will try and why ? ... For me , M1 Truck & SUV 5W30 synthetic because it has 10% ~ 15% more detergents and anti-wear agents than regular M1 . If I can't find that , then Valvoline 5W30 EP is on deck.

M1 5W30 EP for Severe Duty out to 5K miles ?
Severe duty for my Hyundai 2.4L GDI engine is 3,750 miles (oil type not mentioned in owner's manual) ... Curious if using M1 5W30 EP if "severe duty" (i.e. suburban driving of various trip lengths) the milage could be extended to 5,000 miles or even 7,500 miles using again M1 5W30 EP with a Fram...

Mixing QSUD with PPPP ?
I like that QSUD (or new QS Synthetic) is a robust 5W30 but cleaning not quite on par with Pennzoil Platinum 5W30 (which is a thin 5W30 I don't care for in a GDI engine) . *I am considering mixing the two at a ratio of 3 qrts. QSUD to 2 qrts. PPPP hoping that their base stocks are fairly close...

Valvoline Advanced 5W30 vs. Valvoline EP 5W30 ?
My WM sells both oils - I know the new Valvoline EP is supposed to have more moly and detergents (i.e. stronger ad pack) but in your typical 5K OCI has anybody noticed much difference between these two synthetic Valvoline oils ?

Hyundai / Kia 2.4L Theta II GDI Engine Best Oil Sweet Spot
*I have tested various 5W20 , 5W30 and 10W30 synthetic oils in my 2017 Hyundai Sonata 2.4L . With 5W 20 weight synthetic oils the 2.4L Theta II engine runs nice and free - but due to fuel dilution and potential rod bearing issues - the question of not enough film thickness is often discussed as...

M1 0W20 AFE vs. M1 0W20 EP for 12 Month OCI ?
I typically use M1 0W20 EP in a '20 Corolla for 6,000 miles / 12 months and usually hit 12 months usage first before hitting the 6K mile mark . M1 0W20 EP is getting harder to find at WM locally (or on line) , so I am considering the switch to M1 0W20 AFE for the same 12 month OCI ... Is this...

Valvoline Advanced Synthetic 5W30 Users ?
For users of Valvoline Synthetic 5W30 Advanced - what are your impressions to date ? The only two things that may appear to be "average" with the oil are : 1) NOACK is not the lowest but still meets GM D1/Gen2 specs ( 5K OCI's in everything I own now , so may standardize across the board with...

M1 0W40 In 5W30 Rated Applications ?
I have a well maintained 2007 Kia Sedona 3.8L V-6 with 260,000 miles on it . I generally rotate around on sale 5W30 D1/G2 rated 5W30 synthetic oils at 5K ~ 6K mile / 6 month OCI's with a Fram Ultra filter. I was curious if there is any benefit to stepping up to M1 0W40 ? The Kia burns no oil and...

Regardless of the oil, these engines are shaky.
Personally, I came to conclusion to not go past 4k miles on oil change pretty much regardless of oil used in my Sportage. Used many different brands of oil and everything in 0w-20 to 0w-40 range. My choice is in my sig.
For Japanese or Hyundai/KIA the oil doesn't matter much as long as it's decent quality, eg. dexos. Most critical is changing it out at 5k max, and realistically 3.5-4k for most people's driving. Many of the synthetic oils themselves are capable of doing long drain intervals (eg. oxidation and TBN depletion), but GDI engines produce soot that's too small for oil filters to catch and simultaneously very abrasive. Buy whatever dexos oil is cheap and change it out early.

With GDI I don’t suggest anything more than a 5k mile OCI. Now, has GDI improved? On some brands, yes, on others? Not enough. Bottom line, know your vehicle…know how much oil it consumes, how much fuel dilution, your driving tendencies, and get a thorough idea of all this^^ while checking your oil level regularly.

'16 Sierra, been running RGT 5w30 to 7,000ish miles for the past 4 years. I have one change of RGT left in my stash... 106k on the truck total.
'13 Kia Sorento. I had to take this car over from my brother, and have no idea how he handled oil changes, but this car has been severely abused. Now that I have it, I'm feeding it SuperTech Syn 5w30 (the 10,000 mile flavor) and changing it around 4,500 miles. Engine seems fine. 160,000 miles on this car so far.

You went through a lot of work to ‘dis me with such a negative troll reply … Kind of creepy as well … I’m just trying to make conversation here from different angles .

For GDI engines - the best base stocks with the lowest amount of viscosity improvers and NOACK are key to prevent intake valve deposits . Valvoline Advanced and M1 are very good in those respects , Quaker State Full Synthetic is the best in the value price category , Pennzoil Platinum is in the middle and Castrol is surprisingly poor . If I were to keep a GDI vehicle long term I would be concerned with the oil I chose as well as the OCI I decided to run .

I have a 2020 Chevy Equinox LT 2.0L GDI that I have used Mobil Triple Action 5W-30 in, mostly because it is D1 G3. However I've picked up some Mobil 1 ESP 0W-30 for my next OCI. I would prefer it in 5W-30 but I cannot find that in my area. I'm making this change largely because it is C3 and meets MB229.51 and MB229.52 as well as VW 504/507 and Porsche C30 qualifications. My car doesn't require these but they're tough and won't hurt anything and I feel good about it.
10 years with GDI engines. I use cheap synthetic [ store brand or name brand on sale]. Usually 5W30. As long as it meets the latest SAE spec - currently SP. If long trips, in good weather, the OCI will be over 8,000 miles. Short trips cold weather-4,000miles. In my opinion the only thing to avoid with GDI engines is short and cold trips. Gasoline will build up in the oil.
