I want to love PP but can't

When I switched from Valvoline to Mobil1 is wasn't quiet. When my car has been using nothing but Mobil 1 and I switched to Castrol my engine was noisy. When I bought the car I switched from FF to Valvoline I lost power. When I use nothing but Redline and have to cut back on spending and switched to Brand x my car would not start at all.

Faster oil drainback to the pan. Less oil loitering in the engine for soundproofing. Less clingy better flowing oil. M1 has been guilty of this for years. Good to see other synths with the same issue.

How is this not an issue of GrIII+ vs GrII(+) based oils That argument makes more sense- brand is inconsequential. Unless this is, yet another, gratuitous brand wars thread

Because synthetic oil is "more slippery" than conventional oil thus causing the engine parts to move faster causing more clatter. crackmeup hide spank

My brother has a 1997 Honda Civic, and he was using PP for a couple of years, then Ultra since it was first released. This last oil change he used Mobil Super 5K. That's all that was changed, no tune-up was done, the spark plugs and distributor cap and rotor were not changed, and the engine is running smoother and quieter than with Pennzoil PP and Ultra. So much so, he made the comment the other day, we were standing by the front of the car with the hood up and engine running, "Listen to it," he said, "It's purring." Meaning it was nice and quiet compared to before.

I'm a "Pennzoil guy", but I do not use PP or PU in our Honda. The clatter from the engine with that oil in it is unbearable. I guess it's a piston slap type noise, but it persists for many miles, and it sounds like a loose wrist pin when it's very cold out. I've used a lot of different oils in this engine and SOPUS synthetics just don't seem to agree with it for some reason (this includes QSUD). Mobil 1 runs quiet in it, as does most conventional oil, including SOPUS conventional. But this engine is consistently loud on SOPUS synthetic oil. I'm sure it's not "in my head". My wife comments about it, so she can hear it, too. I've been conditioned to think that Mobil 1 is "loud", and indeed it was pretty loud in a Chrysler van we used to own. I tried it once in the Honda, expecting to not like it, but I had to swallow my words on that one because it runs great in that engine. Additionally, SOPUS synthetics run very quiet in our Acura's engine. That engine doesn't seem to care what goes in it...it's quiet on everything. So...I learn over time what oils sound the best in my engines. I know they're all 110% capable of protecting the engine. So I buy based on other factors. Namely, price and personal satisfaction.

According to a senior chemist at an oil company I spoke to you get a better cushioning effect from a mineral oil due to the differing particle sizes compared to the uniform synthetics.

What oils are quieter? Friend of mine has a 2005 Accord J30 and it is super noisey on cold mornings. Quiets right up once it is up to temperature. He doesn't change the oil .... and uses the quick lube stuff , so this is more out of curiosity than anything.

I really don't understand how one oil could be more "smooth feeling" than another. I've tried so many different oils in many different cars and I've never noticed a difference, nor has anyone besides myself that has driven those cars. Maybe my butt dyno isn't as well calibrated? grin2
