Engine oil Castrol or Lucas

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.

Castrol/Mobil1 5W-40. On my JK I change it every 7000 kilometres MAX

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 use castrol 5w-40 european vehicle. fully built and no issues at almost 30k

I use the Castrol Edge oil. I was doing 7500 mile oil changes and on this last one bumped that up to 10k miles. I sent out the oil for analysis to decide if I want to step up to an even larger interval. The comments left by the tester: 'Your CX5's engine looks good in analysis! Your results look really good by comparison after the 10,000 miles. Metals are all within good wear ranges, with iron even showing below-average steel wear. Nice! Titanium is just an additive in Castrol. Very nice! Go 12k miles next fill.' I will heed their advice and go 12,000 miles on this next one.

I used Castrol oil and was not satisfied but this oil till date has helped alittle with consumption as well.

Hi, I have a MK6 2.5L Golf that I changed the oil in at 78,510 miles (126,350km) and is currently at 81,260 miles (130,775.3km) only 2,750 miles (4425.7km) later. I happened to catch a ticking so I checked the oil and the dip-stick/oil pan was bone dry.
