Thank you. I will go with amsoil from now on. I tried them both and noticed a small difference with amsoil but I did noticed that my car would accelerate a little better. I also noticed same with Royal Purple XPR but that oil is very expensive.
One of the best but not always. I have seen oil analysis reports that redline oil in some cases has beaten out Ames oil signature. It depends on the engine so you have to do lab analysis to compare the different oils.
There is no need or benefit in changing oil every 5,000 miles when it's formulated for safe extended drain intervals many times over 5,000 miles. Safe extended drain intervals can save substantial sums of money in unnecessary oil change costs.
@@HiTechOilCo it really is based on the engine and use and oil used. It’s not unfortunately a blanket statement across the same generation of engines because testing there’s variations with many factors involved numbers towards the wrong direction. Basically you need to do an oil analysis every time you’re experimenting with something.
I used LM 0w-20 for 2017 Volvo XC90 T6 125K miles. I noticed oil burning smell coming from engine bay and soot in tail pipes. Oil levels didn't change (meaning no consumption) though. I thought it was the thin oil causing the issue. Switched to 5w-30 Pennzoil Ultra Platinum and the burning smell and soot in tail pipe are gone. Based on this video, it looks like I might be ok to 0w-20 PUP?
@@repairvehicle how would disagree. Even the best oil has some evaporation which they show on the data sheet and percentage. If you have a turbo charge intercooler, you don’t want any oil as it increases. Also, if you have a diesel oil will make the soot very sticky in the intake manifold. You need to make sure there’s absolutely no oil in the intake system with a diesel to not plug up the EGR and intake manifold. This has been proven in the diesel forms before and after cleanliness with the cans, even using high-quality oil like Ames oil or redline oil and fantastic HPL oil
Again you are sharing just your opinion, show me some evidence that backs up your statement. Are you a person who cares about facts or person that doesn’t care about facts?
I just bought LM full synthetic 0w20 for my 2021 Mazda CX-30 non-turbo. I usually go with Pennzoil full synthetic and change every 4,500 miles. Now I'm wondering if I'm going to have to keep an eye on my oil level much more often 🫤
Repairvehicle, good video but you are comparing one of the best oils Amsoil makes, to Liqui Moly middle tier oil -I am told by my technician that Liqui Moly Molygen is one of the best they make.. I would be curious to compare to Amsoil Signature Series
Top Tec 4200 is mid tier oil. Mostly Class 3 hydrocrack base oil. An IR analysis from 2016 revealed 1-3% ester content and 10-20% PAO. Nothing special really. Additive package is also so average its not even worth mentioning. NOAK is 9.5% while the Amsoil is 7.1%% indicating that the Amsoil has better quality base oil, probably significantly more PAO and maybe GLT blended in to. Atleast Shell GLT is superior to standard Hydrocrack Base oil. Around 7.1% is really good for a 5w30. Most are above. I know many 5w40 oils that are not better.
It’s not possible for pennzoil to come up first in evaporation because even specs says that for pennzoil. Older formulas made not from natural gas of pennzoil ultra 5w-30 were slightly better than Amsoil for evaporation rate by only 0.1, not even one percent difference. Natural gas oil is like natural gas evaporates much faster
Only way to know which is best. Send the used oil to the lab test. They will give you the chemical and engine wear numbers to prove which is best. Not so much experience or how it feels in your hand. Maintenance fleet manager want numbers to justify the price and the claim of being the best oil. What are the warranty for engine life? 100k or 5 millions miles? Trucking companies put 100k+ miles a year on their trucks. That's how we make money - on the miles, not the repairs
@repairvehicle you tested amsoil against a lower quality of LIqui Moly. Call then and talk to their engineers. They will definitely give you all the scientific data you want demonstrating it's better than the oil you tested Amsol against.
Their specs says it’s low quality oil and it’s not a best oil they sell. You will never speak to the engineer when you call, you speak to customer service that will tell what you want to hear.
@@repairvehicle Ok, it seems I need to spell this out for you. You tested a lower grade of Liqui Moly against Amsol. This is not a fair comparison. This is like you testing Amsol against Mobil Super and not against Mobil 1. If you aren't willing to concede that Mobil 1 is a better oil than Mobil Super and if you aren't willing to call the Liqui Moly engineers so that they can confirm that Molygen is superior to the oil you tested against Amsol, I really don't know what to say to you.
