Engine oil Castrol or AMSOIL
My co workers wife had a high mileage Sienna 3.0. Oil leaking from every seal. We started using Castrol high mileage, it stopped leaving spots in his driveway and quit loosing 1.5 qrts between oil changes.
I have stuck with manufacturers till manufacturers recommendation is causing issue, like my gixxer leaked entire oil from companies estar engine oil, switched to castrol power 1, no leak, headache gone and happy riding on it for about a decade now.
Using 5W30 since deleting the MDS system from my engine. Amsoil Signature, every 6 months or 8000 km.
Castrol/Mobil1 5W-40. On my JK I change it every 7000 kilometres MAX
I called Amsoil and asked about this many years ago. They said for *my* bike, with the 5 speed tranny, they recommended the same 20w50 in all 3 holes.
the regular castrol gtx high mileage green bottle. I used to use it for a kia rio same as accent and the burning went down a lot
I use 5w-30 Castrol and she runs like a
Dream.
I use Castrol Edge 5W30 LL04 (M). I doubt what you read about sludge is true. Regular oil and filter changes are way more important than which brand you use.
I've tried most of them. I went like 2 years doing all sorts of testing on my car and never noticed a difference. I stick with good old Castrol Edge like the factory recommends.
I am not hating on Amsoil. I am running their engine oil and ****ing hate it. burned off another quarter of a quart in the last day of driving... ive never had this kind of consumption before and there are no leaks...
