Of Synthetic oil and filters (Page 1/4)
kgoodyear JUN 17, 11:42 AM
I got my oil pan put on and will be replacing the oil but it brought up another question. From what I understand synthetic oil does not need to be changed as often. Engine debris, however small gets trapped in the oil filter. The filter I am using is the best NAPA sells. Should one change the filter more often then the oil? Certainly, more oil will need to be added to replace what was in the filter and the plumbing up to the filter.

The other day I watched a YouTube on the quality of oil filters. Man there are some bad filters out there. Fram seemed to be the worse.

The beauty of a solution lies in its simplicity

I use Wix or Hastings branded only and a quality full synthetic oil...… I change every five thousand or once a year as I have never driven more than 2500 miles in a year.

Yes use synthetic oil. It is more durable and better oil in every way. Heat in the Fiero is a little higher to it will provide better protection.

Depending on how you drive Syn oils are good from 6k to 9 k miles. My Turbo with the GM oil condition percentage was 7500 around town.

I use Mobil One exclusive. You can get it at Walmart for only a little more than Dino oil.

Filters just use a goo name brand and change it with the oil.

I use AC Delcos and never had an issue.

Oils and filters are not complicated but some people treat the like politics and religion. These are what work for me and there are other brands that work just the same.

Do read up on the oils as I have gone yo a flat tap pet friendly grade of Mobil One. All oils have had the Zink removed and it is hurting flat tappet cams. That is the real issue today and so few people know about it.

They argue about things that matter little but the real issue.

It is the 15W50 anti wear Mobil One.

On new cars it does not matter as they have roller tappers.

When I had my 3.4 (flat tappets) I used Rotella T, 15W40, to get around the Zinc issue. Never had any problems with it. Still haven't heard of any, six years later. (The car is still "around".)

What does the Mobil One have in it that helps to offset the removal of the Zinc?

Rotella is no longer loaded with Zinc.

I am not sure what the 15w 50 Mobil has fun it is what is recommended for flat tappers on their web site.

Break in on cams Zinc is a must and break in lube that’s replaced it. Once broke in the cam can face a slow wear down.

Thanks for that. I had heard that about Rotella, but I sold that car six years ago.
Everything I have now has roller tappets, so I haven't paid attention.

Correct me if I'm wrong, but I believe the Mobil 1 European formula also has the higher zinc levels. Comes in full synthetic 0w-40, which is a little closer to the GM recommended 5w-30.

Add a bottle of ZDDP when you do the oil change. Read this also https://www.thoughtco.com/d...-urban-legend-726162

I use a moly additive as a work around for the flat tappet issue.

I was told putting full syn in a engine that has had dino oil in it since new with high miles on it by now will kill it because the new syn will basically break down all the gunk that's plugging the leaks in bad seals. Is there anything to that? If its a new or fresh rebuilt motor go with synthetic from the get go though.
