Not all Synthetic Oils are the same. What to look for.

  • Flatirons Tuning Tech Tip - Not all Synthetic Oils are the same. What to look for.

    When it comes to picking an oil for your car, there are a ton of options now if you are looking for a synthetic oil. But what do you look for?

    Synthetic oil has been changing over the last 10 years or so for a number of reasons, and we decided it would be helpful to put together a video that goes into detail about what the different types of synthetic oil are, what some of the popular additives in oils are to look for, and how some certifications, especially an API certification effects those.

    Hopefully this video helps, and thanks for watching!

    Amsoil SS #1, the Best bang for the buck full synthetics = #1 Valvoline High mileage synthetic , #2 Mobil 1 syn...Google highest psi motor oil...A long detail Petroleum Engineers test is posted on many oils PSI levels...Amsoil is like 130,000 psi, Valvoline HM synthetic is 126,000 psi...For the money, Valvoline syn #1..Please note, the oil engineer says any oil 100,000 psi or higher is Excellent Top notch engine protection oil.

    Great vid! I currently use Motul 8100 X-Clean + 5w30 on my G37. So far so good, but what's difference bw that and the Xcess and Eco that also come in 5w30?

    Is it safe to run 300v in a daily, and for how many miles. I assume it doesn't have as much additives for longevity of oil as normal oils have. I ask because sometimes I like to push it and want the best for my engine. Thank you and great video

    Hey I was looking at the Motul stuff and was wonder what the main difference is between the Eco and the X-cess was. I have a 19 STI and it burns the oem oil like mad, but doesn’t burn better oils I’ve tried (royal purple, ams oil) I change every 3000 so oil life isn’t my concern

    Great information video!    Have you  ever noticed when a oil lab tec takes a oil sample form a new bottle for testing he shakes it first?    Why....most of the additives have settled to the bottom of the container, especially if on the shelf for any length of time.  I always shake every container before pouring into any engine.  Thanks

    I noticed that Amsoil wasn't included along with these top shelf oils. Maybe because it is inferior to the brands featured in this video?

    I just want to know that if there are oils that are better why are they not readily available in stores

    I've been using shell Rotella T6 for the engine and shell spirax S6 for the drivetrain with no issues so far, holds up quite well for smell and sight test between change intervals. I've seen Rotella T6 all over the forums but didn't hear any mention of it in the video. Any personal thoughts on it for long time use?

    Pennzoil Ultra Platinum is synthesised from natural gas/methane.What group is that.

  • Barry Thomas
    Barry Thomas   1 years ago my neck of the woods zinc was removed from all engine oils with the exception of Diesel oil. So if you need zinc for whatever reason, you just bought diesel oil. Now after a bit of lobbying from owners of vintage and veteran cars we now have Synthetic engine oil that is labelled "Full Zinc anti-wear additive package" .Although there is nowhere on the bottle or on their web site that tell you what percentage of zinc = full zinc.

    Amsoil, Redline and Motul are just about the best oils available but are pricey.

    Oils that are labeled full synthetic are not 100% synthetic, only oils labeled 100% synthetic are 100% synthetic.

    ENEOS Sustina have group VI synthetic base. Their viscosity super stable, especially easy to know the different with Valvoline Synpower I used before in winter. My car operate like the engine already at operating temperature but temp gauge still at all the way down C.

    BG makes their own oil and they don’t have it API certified. It’s supposed to be an excellent full synthetic engine oil

    Mineral based oils are compatable with virtually all plastics and rubber.......Group 4 and group 5 oils can destroy many kinds of plastics and rubber.......With the growing amount of plastics and rubber used in modern engines, you better be 100% sure that the oil you are using is compatable with the polymers used in the engine.......If your manufacturer doesn't specifically say the oil is approved for their engine, you are taking a very big risk.

    You guys should check out the BG 5/30 full synthetic. I use that and their MOA110 and don't experience nearly as much oil consumption or blow by as I did with other oils in my MY8-14 sti. (mild build, track days every other month or so)

    This was a solid video. Really gets some new information out there on YouTube. Since the FA20DIT has naturally occurring carbon build up on it's intake valves from its EGR system, would a low SAPS or high SAPS oil be the preferred choice? I've been using Eneos 5w30 for the time being, and am unsure if I should switch to an 8100 or say with Eneos.
