This is Mobil 1. It will not cause wear. This oil is great and perfect for an older car like yours that is not currently leaking oil. 10W-30 would not have been my choice I would have gone with 5w30 but honestly its still top of the line oil for your car. Tell you what. Call Mobil. They have...

I've had the VCM Muzzler for a year in freezing to 100 degree. No issue. Wish I had done it sooner

At 125,000 miles my odyssey had developed a nice leak and was burning a bit of oil. I know because I knew about how much was dripping vs how much the oil level dropped. Usually the burning didn't happen u too the end of the OCI. I switched to Pennzoil HM not Platinum just conventional and in the...

whats with the frames? and was it all years?

If you have a Tundra can you share your experience with me. Has it been reliable? Do you wish you purchased a Ford or Chevy or Ram?

I thought the jury was still out on the cause of LSPI. I don't think they know for sure its high calcium. The only document I have seen was where they reported there "could be a connection to higher calcium levels". the below article gives more detail. https://www.oronite.com/products/lspi.asp...

So I was told by someone that TBN referred to an oils ability to neutralize acids and that it is not in reference to controlling sludge or deposit formation. I was told that detergents and dispersants handle that. My question is do you find that statement true. For some reason I considered TBN...

So I take it no one really knows if thir claim is real.

I noticed this claim on Valvolines website for the Maxlife coolant. Do most of you guys think it's true and could I use it in my Honda Odyssey as well as my Toyota Avalon and Nissan Altima? The leading antifreeze brands claiming “all makes, all models” use a corrosion inhibitor package without...

really ok thats interesting. can you explain? So my big thing is I want to go 5,000 miles on a van that is put to some punishing environments. stop and go over 90degrees short trips of 3 miles lots of idle time waiting for parent pickup and so on. sludge formation/ deposit formation is my...

so i know TBN depletion isn't consistent and that it all depends on the oil but here is my question. I want to use Valvoline Conventional oil just because but the most important thing to me is keeping sludge formation away. With that said VWB has a low TBN 6.8 for 5w20 but PYB has something...

No doubt 0w30 syn would have flowed even better during that first start up period is all people are saying but if it dosnt matter to you its no big deal. As others have said it did its job but don't be mistaken synthetic would have had better flow on its way up to temp. Really conventional oil...

I'll jump in and say the unpopular thing. I believe that with time and research the oils today are indeed better than yesterday's. I believe the newer formulations are capable of achieving better performance throughout the spectrum all without having to do it in a traditional way. Oh the glory...

It's a 1998 and has spent it's life 120000 on Dino changed at 3,000 miles.

Also. Why are the flash points so Close between synthetic and conventional?

Thank you. Good advice. So you feel the 10-30 will hold up to heat better than the 5-30?

To answer that question I recently got burned by switching a older high mileage van from conventional to synthetic so honestly I'm afraid to go full synthetic.

http://www.google.com/patents/US20100022422 If this is what component formulation is all about I'm done pretending I can figure anything out. What is "high temperature shear stable nanographite dispersant". It's amazing just how much chemistry goes into oil formulation. Looks like this is a...
