Is it the approximately $1.70 per quart (with BITOG discount) cost of the Premium over the regular PCMO stopping you from using it? That's what I understand from your post.I realize there are many people on this forum doing 10k oil changes with excellent results. tig1 (I think) comes to mind. I just can’t bring myself to do this with the synthetic oils I have been using. I would go 10k with HPL, but the cost differential would be double. If the lowest tire HPL PCMO came in 0w20 or 0w30 I would do this in a heartbeat.
Seriously the Mobil 1 EP could go 7500 miles easy and you can get it on Rollback at Walmart for $26.47 a Jug (five quarts). Two Jugs online from Walmart you get free shipping.HPL PCMO Premium 0W-20 in a 4 gallon case would be $230.37 after discount, taxes, and flat rate 2nd day shipping. That's $14.40/qt.
Mobil 1 EP 0W-20 is ~$30 after taxes at your local Walmart for a 5 quart jug which is ~$6/qt.
Your engine requires 6.5 quarts (IIRC) of oil. Say you went ahead and bought 3 jugs of Mobil 1 EP 0W-20 to have 15 quarts on hand.
Mobil 1 EP 0W-20 = $6/qt x 6.5 quarts = $39 per oil change
HPL PCMO 0W-20 = $14.40/qt x 6.5 quarts = $93.60 per oil change
Mobil 1 EP 0W-20 = $39 / 5,000 miles = $7.80 per 1,000 miles
HPL PCMO 0W-20 = $93.60 / 15,000 miles = $6.24 per 1,000 miles
So you see, the HPL is actually cheaper in the long run. It can easily handle 15,000 mile annual OCIs. I went 20,500 miles on their 5W-20 recently (not even the premium) and still had good TBN, no shear, wear rates normal, etc...
If cleaning is your main concern, EC30 does not offer as much "cleaning" as their oils.What about buying a stash of the EC30 and using a quart every oil change? You can use your regular oil but still get the cleaning benefits of the EC30.
I see the problem now.I did look at the Premium Plus version, but it is only a $10 difference for 6 quarts. The least expensive version does not come in 0w-20.
I should have said HPL PP 0W20. HPL PCMO 5W20 is a great alternative, all things considered.OP, I have massive experience with using HPL oils in Dynamic Force D-4S engines.
The correct answer is HPL PCMO 0W20.
15k mile/1 year OCI.
HPL oils have other worldly stamina and offer excellent protection.
Well, HPL does make an Overkill 0W-20 ... "When good enough isn't good enough"Besides the 10k filter changes the rest of your regimen is way over the top. I mean using EP oils or HPL seems like a total waste especially for 5k miles on a Lexus engine. All you really need is a regular shelf synthetic. Don't get me wrong your oil choices are great but seem like definite overkill.
Seriously the Mobil 1 EP could go 7500 miles easy and you can get it on Rollback at Walmart for $26.47 a Jug (five quarts). Two Jugs online from Walmart you get free shipping.
But what if it is run consistently every OCI? It was just a thought.
Your # 3 is the way to go.I have been following the HPL threads with great interest. There is no doubt in my mind that this oil is superior to "off the shelf" synthetics. I have questions as to whether the extra expense is worth it.
A bit of background:
I have been changing the oil in my 2015 Lexus GS350 with 0w-20 Mobil 1 AFE, Mobil 1 0w-30 ESP or Castrol 0w-20 Edge extending performance at 5K intervals with oil filter change at 10K intervals since new. The filter comes out perfectly clean at these intervals. The car now has a bit over 60K miles.
At the last oil change, I added one quart of HPL engine cleaner in place of one quart of oil to do a bit of engine cleaning. I will be changing the oil and filter at 5K and repeating this process for one additional oil change. Here are my questions/thoughts in order of increasing expenses.
1. This alone should be sufficient to clean anything left behind in previous oil changes and I will just continue what I was doing initially.
2. Go back to my initial oil change protocol, but substitute one quart of Mobil 1 or Castrol with HPL super car oil.
3. Run one oil change with HPL super car formula for 10K and then go back to what I was doing initially with the addition of one quart HPL super car per oil change (or not).
I realize running the HPL oil for all future oil changes would be ideal but at approximately $120 for each oil change this would be about twice the cost of the above mentioned oils. It is only twice the cost because I figured in changing HPL every 10K and the previous synthetic oils at 5K.
By the way, I drive about 15K per year.
Appreciate your thoughts.
