What Motor Oil is everybody using?????

[cam3439]

I was told it was better to use a higher w in the winter, not less.

No!!!!!! It's the opposite. If you get the higher W it is a thicker viscosity and thus cannot flow through the engine as easily, especially during start up. It is recommended to use a lower W during the winter and higher W during the hotter days. I live in Texas and it gets pretty dang hot down here, and not that cold so I use 10W-30 on my hoe. If you live up north in the freakin cold then it is highly recommended to use 5W-30 or even 0W-30, especially during the winter.

Mobil 1 Full Synthetic 5w-30 or 10w-30

same for me too

Just the opposite. An oil that is thicker takes longer to flow throughout the engine when literally ice cold. As the engine oil heats up, it won't be any different than a 5w-30 or a 10w-30 at the same given temp.

Alright thanks for clearing that up.

Mobil 1 5W30 High Mileage Formula and a Fram TOUGHGARD or EXTENDED GARD, the regular Frams come apart inside and don't filter as well.

I run Mobil 1 Syn in all my vehicles now. When I was younger I used Penzoil. Mobil 1 filter too. I am going to run 10-30 this weekend.

Chalk Up another one...

Mobil 1 5w-30 Fully Synthetic and Fram Tough Guard filter. I change every 5k.

 

[WICKEDOWESIX]

Mobil1 5w-30 fully synthetic and Mobil1 M1-206 oil filter changed ever 3K mi or 3 months.

 

[IRQVET]

Mobil1 5w-30 fully synthetic and Mobil1 M1-206 oil filter changed ever 3K mi or 3 months.

+1 on using full synthetic and changing ever 3K miles. Some people say you can go longer but I guess old habits die hard.

 

[Sellncars]

Mobil 1 Full Synthetic here..10W30

 

[blizz]

i'm gonna start using a 50-50 blend.

Is there any disadvantage/harm in using a plain AC Delco filter designated for my car? Or are there better options to go with if I run Mobil 1 full synthetic 10W30?

And should I bother with an oil additive? If so, which and why?

I don’t know of you realized this was a thread from 2010? You might get more responses starting a new one.

Last question first, I don’t believe in additives. Maybe decades ago, but modern oils have everything needed in the bottle.

For a well aged engine, the one thing I would NOT do is long intervals between oil changes. Because as rings wear etc. you’re getting higher levels of contamination than in a fresher engine. So change oil frequently is the main thing. Better to use Walmart Supertech at 3k miles than buy expensive name brands and eke out extended oil changes. No matter what oil used, it can only suspend a certain amount of contamination, and once that’s exceeded, you’ll be depositing sludge in the engine.

Filters are always an interesting topic, many brand names are sold out of a relatively few factories. My .02 is as long as you’re not buying the cheapest 2$ filters on sale then the middle tier are all quite good. Nothing wrong with AC Delco. And probably little to no benefit from more expensive options.

I did realize that, and I'll probably make a new one I just wanted to give this thread a refresh. I've heard that as well, and it's not been very long since my last oil change but I think its time. I'll probably just stick with AC Delco, its been working for me so far.

What if I told you it doesn't matter

I use Pennzoil 5W30, and Fram filters. The 5L jug comes on sale every couple weeks, and I pick up 2 when I am about to do an oil change. I have to replace the oil pan gasket, so I don’t have to keep adding so much between changes.
