Hello happy people! We just bought a 97 Camry with the 5S-FE engine. Now as far as I know, these engines have problems with sludging up. This car has 290,000km's on the clock and they are mostly highway miles. The previous owner followed the regular OCIs and there doesnt seem to be a problem with the way it run, other than a noisy valvetrain over 4000rpm. Looking through the oil fil cap shows a lot of varnishing, but again thats not really the best diagnosis.
Would you guys recommend flushing this engine out with kerosene a few times at the next oil change? Also I wanted to use Mobil 1 5w-30 or GC 0W-30 oil afterwards as we head into winter. Which of those would you recommend or any other suggestions for oil?
Thanks
