Pennzoil Ultra Platinum 0W-40 Motor Oil vs ACDelco DexosD 0W-20 Oil Change Kit

These are not interchangeable oils. The Pennzoil Ultra Platinum is a full synthetic 0W-40 for gasoline performance engines, including SRT Viper and Demon applications, and it carries a strong 4.8 rating from 873 owners. The ACDelco DexosD kit is a 0W-20 synthetic blend for light-duty diesel engines that require the dexosD spec, and it comes with a matching filter. Buy the one your owner's manual calls for; the wrong viscosity or spec can void coverage and harm the engine.

  • Choose the Pennzoil Ultra Platinum if your gasoline engine specifies 0W-40 full synthetic, especially a high-output SRT or similar performance V8, and you want a filter included in the box.
  • Choose the ACDelco DexosD kit if you drive a light-duty diesel that requires dexosD 0W-20 and you want the correct OEM-spec oil and filter together.

What reviewers say

Pennzoil Ultra Platinum 0W-40 Motor Oil

  • 4.8 / 5873 ratings

Owners rate it highly, with most praise going to how quiet and smooth their engines run and to its use in SRT and other high-performance cars. A few note the cost and the paperwork needed for the warranty.

What people mention
  • Engine smoothnessPraisedOwners say the engine idles and revs more quietly after switching to it.
  • SRT fitmentPraisedViper, Hellcat and Demon owners like that it carries the Chrysler MS-12633 approval.
  • Heat resistancePraisedDrivers in hot climates report stable oil pressure during hard driving.
  • CostCriticisedSome buyers say it costs more than other full synthetics of the same grade.

ACDelco DexosD 0W-20 Oil Change Kit

  • 4.9 / 514 ratings

Ratings are very high, and buyers describe it as the correct OEM oil and filter for their Duramax diesel.

What people mention
  • Oil specPraisedBuyers value that the oil is dexosD-licensed and matches the engine's requirement.
  • Filter choiceMixedThe OEM 30-micron filter is accepted, but some would rather run the finer 10-micron upgraded filter.
  • ConveniencePraisedHaving oil and filter together makes the change simple.

Questions and answers

Can I use the Pennzoil 0W-40 in a diesel that calls for dexosD 0W-20?
No. The Pennzoil is a gasoline-oriented 0W-40 and does not carry the dexosD license. Using it in a dexosD diesel can affect emissions equipment and warranty coverage.
Can I use the ACDelco 0W-20 in an SRT or Demon?
No. Those engines specify 0W-40, and a 0W-20 blend does not meet that requirement. Use the Pennzoil or another oil that meets the 0W-40 spec.
Which lasts longer between oil changes?
Follow your owner's manual interval. The Pennzoil full synthetic generally holds up better under high heat and heavy load, while the ACDelco blend is built for the diesel spec it serves.
Is the Pennzoil worth stepping up to over a conventional oil?
For a high-output gasoline engine, yes. Full synthetic resists oxidation and sludge better, and the warranty program adds coverage if you enroll and follow the rules.
Does the ACDelco kit fit my truck?
Only if your truck's manual specifies dexosD 0W-20 and an ACDelco PF66 filter. Check the filter number and oil spec before buying.
