This is my second oil analysis. Used 5W-30 Havoline GF-4 for about 6 weeks. Half of the miles were on highway, including a 650-mile trip in a day. Half-way through the OCI, I changed the air filter with a new Toyota air filter, and the oil filter - the PureOne started to leak, and I replaced it...

My Mazda’s engine has developed a rear engine seal leak at about 60K miles. It is not a major leak (uses 1 quart every 3000 miles). Last year, in May, I switched to Castrol Syntec Blend (5W-30), and 100 miles later I noticed that oil was leaking onto the exhaust, producing some smoke. I drained...

Anybody knows where I can find info regarding what brands of motor oil meet the GM standard 6094M? Havoline, Mobil or Citgo websites say nothing about meeting this standard, but Castrol mentions it. Or, is it a fact that all API SL / ILSAC GF-3 oils meet this standard? Can you refer me to a...

Here are the lab results of my '96 Mazda 626, 4 cyl. auto, on Northland motor oil - Blackstone labs: What do you think about this oil? Does it look like a reasonably good oil? For those not familiar with it, it's produced and widely used in Iowa, and sells for $1.60 at Advance Auto Parts...
