Hi Guys, I’m trying to determine the best combination of oil/OCI approach given the circumstances of my current vehicle: 2004 Toyota Camry SE, 2AZ-FE Engine 4cyl engine. 5-Speed manual transmission Approx 210,000 km Was previously driven between 5000-6000 km/month. Oil changes were monthly affair @ a quick lube place with either conventional dino or high mileage 5W-30 ( brand was possibly Quaker State as it was serviced At Jiffy Lube) Since I took ownership in August 2008 I typically do between 500-800 km month, with majority of it short-trip city driving to work and back. I’ve only had two oil changes on the car (approx 6 months apart), both at the dealership. Engine oil was Toyota 5W-30 conventional and OEM filter. I have not had to top off the engine at all (except when I first got it when it was 2/3rds of a quart low for some reason). I have not had any UOA’s done. I’m following the Toyota recommendation of 8000 km or 6 months between OCI’s for now. In order to ensure the engine is adequately protected from the frequent cold starts in the winter I’m giving consideration to the following: Block heater, Oil Pan Heater, Synthetic Oil The last point I’m not sure the best approach to go and I’ve narrowed it down to the following four oils (mainly because I can get these relatively easily): GC 0W-30 (available at local Walmart, and yes it says Made In Germany on the back) PP 5W-30 Supertech Synthetic 5W-30 or 0W-30 Amsoil Signature 0W-30 I’m hoping to get some sort of either consensus or suitable alternatives to ensure I’m taking maximum care of this engine. Also, I cannot seem to find anything but FRAM filters everywhere I go (Walmart, Canadian Tire, Part Source) as I was looking into possible alternates to the OEM filter. Cheers, P.S. Thanks in advance.
