searching the forum I found many guys just using Walmart oils and stuff like that and since I am changing my oil every 2500km everything will be fine, but I don't feel so good with that advice! Up until now I was using Castrol power 1 10w40 and after every oil change it was like water, not thick at all (even though it has pretty good reviews). Any recommendations? Brands, viscosity and if I should use synthetic or semisynthetic oil...
IMO, with frequent oil changes, synthetic oils are a waste of money. Forum member Buickguy put over 100,000 miles on his 1987 CMX250. He used Castrol GTX and I believe he changed it every 1,500 miles (approximately 2,500 km). Any good quality oil, that doesn't have friction modifiers will provide excellent protection. All oils that meet JASO standards would work and don't contain friction modifiers. One such oil is Shell Rotella T4 15W-40.
I don't think you can judge how good an oil is by how thick it appears.
