Engine oil Mobil or Lucas

Mobile one is best in every single case, unfortunately its the most expensive for this reason.

I’ve heard valvoline is good too. I use Mobil 1

I personally lean towards affordability, so I run Mobil 1 0w-40 because the local parts stores run sales for $35-40 pretty regularly.

I had a tiny bit blue smoke and thought it was sticky rings.

Ran mobil1 5/30 and it's gone.

Personally I've mostly been using Mobil 1 15w50, as it's almost never run in the winter.

Mobile one full synthetic hands-down. I have a 2004 Toyota Corolla and a 2007 Toyota Tacoma I’ve owned both since brand new and now both have over 260,000 miles apiece . I have only used Mobil one full synthetic changed every 5000 miles. just took a bore scope to look into both engines a few months ago. They look like they’re brand new. Almost no varnish. Absolutely no sledge, never had any problems whatsoever with these vehicles. It’s insane.

my vehicles use only Mobil 1 oil.

I have used Motul and Castrol before and I found the Mobil oil to perform and keep the engine cooler and smoother on my triumph.

I used to do 10k mile oil changes with Mobil 1 EP.

At my 18,000 mile service, barely dropped off full. V.W.they told me at the service has now went with Mobil 1.3,000 miles later down now a 1/2 quart.
