What oil does everyone use?

I currently use Castrol GTX High Mileage 5w-30 with a bosch premium oil filter.

I had several people tell me to use the toyota filter because it will hold the oil in it with the special valve in the filter. But my filter mounts upside down so the law of gravity should keep it full of oil and it has that special valve too.

I have used Lucas Oil Stablizer in it one time.....but its so thick i am scared to it it again.

Amsoil XL and a Denso or Purolator Pure-One filter. I change my oil twice a year now...

 

twice a year?? you dont worry about the motor getting dirty? to me over 5k miles is a stretch even for syns

 

Mobile 1 10w-30 Full Synthetic With A FRAM Tough Guard Filter
(next oil change I will be changing the oil and updating that oil filter to something bigger...)

 

for the 6-9 months of the year when its pleasant outside - 10w30 mobil 1 clean 7500(yea i know synthetic blend...) with whatever highlife filter i can find at the time.

in the summer months, when average temp is above 100, i run 20-50. doesnt break down due to heat like the thinner oils do. ill sacrafice a bit of performance and mpg to save my engine when its hot out.

 

I guess I am the only soul that uses castrol.

 

Mobil1 5w-30 and a Fram filter

 

Oil gets dirty before it breaks down. If you are only going to change it twice a year I suggest getting a real good filter like a K&N premium filter with a synthetic media and change it regularly.

 

I would seriously consider changing your oil filter brand. Search the forums for Fram information, you can look on almost any car site and no one recommends Fram.

 

Fram looks like a cardboard box crinkled up and shoved into a metal canister. That is if you cut it open.

 

5w30 Valvoline and yota filter every 3k miles. Can't afford or really justify using synthetic.
