Engine oil Mobil or Castrol

Mobil 1 full synthetic 5w20 or 5w30 is best in my opinion, and I’ve always just used a fram ultra from Walmart never had any problems and my K20 seemed to enjoy it

Last change oil ko 5700km di naman sumabog swabe parin manakbo

Oil used was Castrol's Power 1 5w-40

My tacoma has 352000 miles have always put mobile 1 in it

I personally have run Mobil1 0w-30 in my GSR for the past 250,000+ miles, since back in the mid-2000's.

Of course, after I bought it I dropped the oil and ran what I like to run in my cars/trucks which a Mobil Delvac product 5w-30. It’s a synthetic but it’s more used for the heavy duty market. I checked the oil some 4000 miles later and it had a reddish look to it just like yours. After the next oil change I never saw it again.

Yooo this happened to me, have you used a high mileage type of oil? Apparently when they start to burn up they can change to a reddish hue, I went back to normal Mobil 1 and it’s back to gold

I’ve moved to Castrol edge for my 9th gen.

Castrol edge and OEM filter for turbo.

I found Mobil 1 0W-40 to allow a lot more timing chain and lifter noise, especially at startup but even after, then switched to Castrol Edge 5W-40 and the noise suddenly wasn't there. I've used it ever since.

I used castrol edge on my last change but I don't like the way the oil looks after a few months of driving. Of course it was extreme temperatures down here in South Texas. Wonder if the extreme heat caused my oil to look kinda jello looking haha.
