  1.  @wallmethod  Nothing help, selling it and buy newer car with dual injection or port injection solve the issues 100%.

  2.  @functionalvanconversion4284  just follow the specs. There are some oil with low and very low ash for GDI cars. I think only Ravenol still use full synthetic with PAO base or group IV. but many group III HC synthetic oil are very good these days and even mobil 1, Total, Castrol Syntec cannot put full synthetic label in EU anymore, because they contain less than 70% PAO. They only say synthetic not Fully synthetic on the label. In USA, they can claim full synthetic with group III oil.

  3. It does not look like typical high grade brake pads from local Advanced or Autozone. Wagner, Duralast Gold are very good and ceramics. Last long, no corrosion, and as good as the OEM from Toyota or Nissan especially the midrange like Duralast Gold with lifetime warranty nationalwide from Autozone. Advance Auto has no interconnection and we need to keep our receipt.

  4. Good year vector4 seasons gen3 has better rolling resistance and treadwear than Michelin crossclimate+ and also cheaper. A good thing about any premium tires, they perform better over the whole life, life longer and at the end are cheaper because tires mounting service is not cheap. Easily cost us $60-$100. With typical 16" all seasons tires cost about $70, and cheap all seasons are about $50 but with only 60% lifespan, premium tires is cheaper if we use them till the end of their life than cheaper tires. Worst tire that is so popular in USA is Chinese Primewell, with 10-20% more, we can get Firestone tires with 50% more tirelife and better quality.

  5.  @nickmccain6598  Typical midgrade brake pads from local Advanced or Autozone, Wagner, Duralast Gold are very good and ceramics. Last long, no corrosion, and as good as the OEM from Toyota especially the midrange like Duralast Gold with lifetime warranty nationalwide from Autozone. Advance Auto has no interconnection and we need to keep our receipt. Wagner grip is not as good as Duralast gold. Toyota also sell cheaper ceramics pads with YZZ part number, basically aftermarket in Toyota box. Original pads are usually semi-metallic from Advics or Aisin but cost almost 2x more than YZZ part number. If you want OEM like and quality aftermarket from Akebono or Advics are the best bet. Advics USA 99% are identical with original OE part and better than Dealer parts with YZZ part number. EU suppliers like Bosch, Zimmermann, Textar, Brembo, Hella Pagid, Meyle are usually ECR90 certified (80-120% specification of the OEM).

  6. Using Toyota most reliable engine make it invalid. Mobil 1 should use FIAT Chrysler, VW, BMW, or GM engines only.

  7.  @craigbadder4372  it make 30k miles if you want

  8.  @functionalvanconversion4284  the difference is negligible. Any oil that is certified by ILSAC VI or API sn plus or newer, they are good. There is strick standard and certification in engine oil.

  9. Great information, it means 30% improvement that still will not solve intake valve build up issues in most direct injected engines from Hyundai, VW, BMW, Benz, and Honda.

  10.  @therealSIRBOOM  Catch Can reduce a bit of carbon deposit but the main cause is the actual intake manifold design itself. Especially if it has an EGR line or any kind of recirculation system.

  11. Dual Clutch Transmission need Clutch Replacement as one of the fate after certain usages. Could be fast could be slow depends on who drives it like Manual Transmission car.
