Grammar

Left Out Preposition?

Hi,

"Semi-synthetic engine oils are produced in a complex process, but are therefore considerably better quality, especially their aging resistance and thermal properties."

I think there's something wrong here about the grammar of the underlined part. Shouldn't it be "but are, therefore, of considerably better quality" or "but are, therefore, considerably better in quality" or "but have, therefore, considerably better quality" ?

I'm also doubtful about the use of 'but'. Shouldn't it be 'so' or 'as a result' ?

Thank you.

  • It depends on whether you think the writer sees 'produced in a complex process' as likely to improve quality, or not to improve quality.
