Hello, I have a 2000 Camry with the 2.2L 4-cylinder. (The 5S-FE for the Toyota guys) This known sludge motor is a DOHC engine with shim and bucket lifters (solid lifters), 16 of them to be exact. I have checked the clearance between the cams and lifters, and all 16 lifters are within factory limits. I drive about 16-20 miles a day here in Texas and “cold” for us is 40*F. I run this motor hard and it revs over 4K daily just to keep up with traffic. It has been a very dependable engine and I have replaced the valve cover gasket, timing belt and water pump. I have changed the oil every 3K with conventional 5W-30 or 10W-30, with whatever I have on hand. The engine doesn't burn oil and has 103K miles, which is nothing for this engine.
Here some pictures to show the condition of the engine. You can see come cam wear on the lobes.
Here's the question, I’m trying to find a brand of motor oil that can help reduce noise from the top end. It has the “normal” sewing machine noise of a non-hydraulic lifter but prefer it to be quieter. I think I'm so used to hydraulic lifters engines that mine just didn't feel "right". I have several motor oils on hand that I can use on my next oil change, 1K left. I have research endlessly on BITOG and other forums and have conflicting answers. Here’s what I have:
10W-30 SN Chevron Supreme, I’m currently using this but haven’t hear any different in noise.
10W-30 SN Quaker State Ultimate Durability, I have several quarts in the garage.
10W-30 Rotella T5 (CJ-4/SM), I have a gallon that I may use since it is dual rated for gasoline too.
5W-30 SN Peak conventional, I have 3 jugs for other cars.
These engines can run on almost anything, Australia spec Camry use 15w-40. I’m interested in using the T5 but not sure if it will hurt or help. I also have a Purolator Synthetic oil filter on the shelf for this car too. Which of these oils would you recommend or is there a better one you would suggest.
Also, my valve stem seals are leaking (like most 90's Toyotas) and it gives off a blue puff on start up now and then. No HM oil will help the seals but I want to avoid oil that may hurt it.
