Just the opposite. The Pegasus was the original logo/company. Most people are just used to seeing the premium brand mobil 1. Yes mobil 1 syn is better than mobil syn, i didnt even know mobil had a syn...

Quote from nightanole :
If you have good seals, or new seals, there is no point in "spending extra" for high mileage oil. However if its the same price or cheaper, its not a decrement either. Its not going to cause seals off the showroom floor to swell. Its only going to cause degraded seals to swell a bit, at best. If you have a sheet box, the grime that filled the degraded seals may be the only thing keeping it from leaking. Switching to plain synth may be a bad idea, as its gona clean the grime. There is hope that synth with sweller could give a bit of life left to the seals.

Its the same with buying extended interval oil. there is no point in paying extra, if you do 3-4k oil changes with it. Infact it may be worse since its got more additives, and less "oil".
I actually just did an oil change, using a HM synth blend, since that's what I had left over from previous oil changes. This was before I replaced or even decided to replace the seals and I figured that with old seals it couldn't hurt. Shortly after I did the oil change I flushed the coolant with some pretty strong cleaner and it took out a bunch of gunk that caused a leak, so I decided to replace the TB & WP and while I was in there also the front seals.

I also removed the valve cover and saw a bunch of gunk in there. I took out as much as I could manually but the rest will have to be removed with several oil changes and running the car in-between for relatively short distances. So I guess it's ok to run the existing HM oil for a bit and then replace it with non-HM oil, if it's not going to swell the new seals much? And should each quick oil change use standard, blend or synth?

Mobil 1 has been well documented beginning 1976 in Popular Science. M1 oil changes recommended 10k miles by Porsche. Mobil 1 is an ester which accommodates pH chemistry changes.

Again its not going to swell a good old seal. Its not going to swell a good new seal. If you are changing every 3-4k and its not "high performance", aka 5w30, good old quality conventional is great. If you are changing twice a year, id run whatever full synth is on sale.

Blend is marketing and worthless, its just there to take your money.

If your engine has tight tolerances and needs water for oil, aka 0w20, i wouldnt risk it, and just buy the premium sheet.

Never get under a car being held by just the jack. Decent jack stands are <$50 and should be used anytime you're under the car.
I use ramps for the front wheels. Easy to drive up and plenty of room to change the oil and filter. Plus, a lot safer.

At work we got in a "can" of turbo oil. Didnt have a pop top, didnt have pull tab. The 30 year old engineer just looked at it in wide wonder on how to get the magic fluid out. I finally stepped in once i saw him walking around with a hammer and screwdriver.

I'm sorry I have a tuned supercharged engine that I redline on almost a daily basis. I need mobil 1 every 5k miles and a wix filter so my motor lasts. To each his own but to me mobil 1 has given me proven reliability.
there is a big difference between that and something like a gm v6 from the mid 2000s. this stuff is fine for daily drivers, i've run supertech synthetic in my dailies and have yet to have one not pass 200k and keep going.

on the flip, you aren't wrong for custom engines. I run royal purple or mobil1 on both my modified cars.

Quote from Beardedgunna :
Don't cheap out on oil or tires.
I disagree, any synthetic oil holds up just fine based on my experience across multiple cars. They're all "good enough" at this point for factory applications, regardless of brand.

Off brand tires as well as perfectly usable. You may compromise in one or more areas such as tread life, grip, efficiency, noise, etc. But doesn't mean you shouldn't use them. You just have to set your expectations accordingly and not exceed their limit
