Then why not buy HPL PCMO 5w30 in 5-gal buckets? This oil has been extensively tested in an incredibly difficult environment and proven capable at 15k OCI. You have several vehicles, so a 5-gal size makes sense, especially with your short OCIs. Why keep testing OTC oils that clearly aren’t capable of what you want, even at 4k OCI??I have trucks with the Ford Ecoboost 3.5 Liter engine and Ford states its Motorcraft 5W30 Semi-Synth is the best for it..but through oil testing I was concerned with it. Basically the oil I put in was 5W30 and the oil I took out was 5W20...and Ford says it can last 10000 miles.
Over the years I settled on Mobil 1 Delvac ESP 5W40 and other 5W40 Euro oils. The Mobil 1 tested very well and was able to last at least 5000 miles without it falling to a 5W20.
So Ive decided to try Pennzoil Ultra Platinum 5W30. The Ford tech on Youtube says to always use OEM parts listed in the manual except for the oil which he holds up the yellow Ultra Platinum 5W30 jug.
So I decided to give this a go in my 3.5 liter High Output Ecoboost to see how it goes. I do get about .5 mpg less using 5W40. One huge benefit in using 5W40 is it quiets down the engine and sounds very refined.
Pennzoil Ultra Platinum I understand is their answer to boutique oils like RedLine and Amsoil. Pennzoil basically decided to make the best oil possible.
I did try Amsoil 5W30 Signature Series in the past and its a great oil...problem is its expensive and hard to source. I got the Pennzoil jug at Walmart 5 quarts for $32....more expensive then other oils at Walmart but Amsoil and RedLine are way more expensive! Basically if an oil cant be sourced from Walmart it will ultimately be too much trouble to locate when you really need it.
So I will give this a go and in several weeks report back on my findings...sending virgin oil sample to Blackstone....
