Thanks. The car came with iridium spark plugs, which Toyota says last 120k miles. Gap on them is fine, no unusual blemishes, except for #4 with dark debris. Nothing unusual in terms of performance except rough idle, which I have narrowed down to engine mounts (idle speed is normal at around 800...

Thanks. JohnG, what are VIIs?

Thank you. Can you recommend any good 5W30 synthetic oils for this car?

2006 Corolla with stock 1ZZ-FE engine, 141k miles, and unknown maintenance history. Oil cap calls for 5W-30 SL. I've had it less than 1,000 miles. Piston crowns are black and only on spark plug #4 is black residue (didn't think to take a photo before cleaning it). No pinging or check engine...

Scuder, thanks for your response. I agree that Ultra is a low volume product. What I don't understand is why. Any insights?

Thanks. 1996 Toyota Tercel 152k miles with stock 5EFE engine. Maybe there just weren't that many made, so that's why I can't find whether this engine has a bad rep of being an oil burner, such as Generation 8 Corollas (1998-2002)? Amazon also removed the Valvoline Premium Blue Restore from my...

Thanks, simple_gifts. On Amazon, I could only find a synthetic blend for 10W-30 (nothing for 5W-30). They also said nothing about being specfically designed to clean engine deposits. Likewise, Valvoline.com says nothing about that and was more spartan as to specific oil grades than Amazon...

dubber09, thanks. How is the PUP considerably better than the PP?

I want to reduce oil burning and clean both my piston oil rings and my piston oil holes without having to overhaul the engine. I reviewed threads in the UOA and this forum, but did not see a discussion of the latest (SN) version of Pennzoil Ultra and Platinum. Pennzoil's website didn't clarify...

Thanks. I found some Chevron Type F in my garage and also Pennzoil, both dino. Where does the Pennzoil Type F fit in the quality category? Thanks

Thanks

Thanks. What does "VMed" mean?

Thanks, everyone. mechjames, would you help me understand how the friction modifiers in Dexron make the pump noisy and wear it out prematurely? Also, does it harm the power steering rack? Thanks!

I have a 1988 Volvo 240 DL normally aspirated with power steering (ZF type). The manual calls for Type F. I'm wondering if I can use synthetic Dexron instead, because I can't find synthetic Type F and have lots of synthetic Dexron? I read an anecdote about the power steering leaking a while...

Thanks. I'm having trouble finding a vendor that sells SAE J2360 compliant oil. Nothing that I found on Amazon, O'Reilly, or Autozone. Have you a link? Thanks
