Shell Rotella T5 oil, zinc in the oil better?

 Zinc in the oil better for longevity?

Found in the comment section of Speedcar99 Youtubechannel:

"shell rotella t5 15w40.  still has lots of calcium and zinc in it to protect the engine.  they pulled the zinc out of t6 under 1000 ppm.  no zinc no long lasting engine."

But might wear a little more on the catalytic converter?

Video: Changing oil and oilfilter on a Starlet from 1997

Here are the video when I´m changing oil and oil filter on the Starlet.

Time to replace the oil in the Engine

Its time! Changing engine oil and oil filter on the Starlet.

Felt like it was time to give the beloved Starlet some service.

I did consider lots of alteernatives for the choice of oil but ended up chosing Biltema Fully Synthetic 5W-40. I´ve used it on some of my earlier cars and have been pleased with it. Specification is API SN which tells me that the oil should be of fine quality.

Here is the oilplug on the Starlet EP91

To get better access under the car I drove the car up on this truck frame.

No problem climbing under the car now. :-)

 I also made a movie, though it might be of interest for you. I will show it in the next post. Have to do some editing first.

Finding a cheap oil, out looking in stores here i Sweden

It´s a djungle out there, and I dont have much knowledge, but I´ll try to pick anyway..


Biltema motor oil or Swedol? Which one should you choose? This seems to be the most oil for the buck here in Sweden? Any opinios? I know this subject has lots of opinions.. :-)

In Swedish: Biltema oljor vs Swedol motorolja..

Big size picture: Comparing semi synthetic vs fully synthetic, not much diffrence ackording to the certification?

Price can be seen.

Front of Biltema motor oil.

These oil are sold by Swedol, a few crones cheaper, but are the better or worse than Biltema? Who knows?

Swedel semi synthetic oil.

The Swedol comes from Q8 oils. Cant be to bad right?

Swedol supergrade oil, only 130 swedish crones. It you anint got hot engine this might work for you.

One of the test standards Petroliuminstitut test and approve are the API (American Petrol Institute) and it starts with "S". The "higher" the second letter, the better the oil. Today's well "SN" the highest. "SJ" is slightly worse. "SH" yet meet lower requirements, etc.

So let us compare Swedol with Biltema.

Swedol Helsyntet SAE 5W-40 (225 SEK) : API SL/CF, ACEA A3/B3, CCMC G5, PD2. 4 liter.

Biltema: Helsyntetisk motorolja 5W–40 (279 SEK)

API SN/CF, ACEA A3/B3/B4, MB 229.3/229.5, BMW LL-01, VW 502.00/505.00, Porsche A40, RN 0700/0710, MB 226.5, GM-LL-025-B.

Biltema is the better choice according to that norm.
