Bought the car back in July 2020. Car has an unknown maintenance history. It is the non VCM variant as it is a 6 speed manual coupe (supposedly VCM causes high levels of oil consumption on these motors) 148k Miles on the clock. Did the timing belt and water pump and spark plugs/ Air filter after I purchased it. OLM was at 100 but the oil change sticker from some quick lube place called for an oil change in about 1500 miles. I ran out the 1500 miles and noticed some oil loss on the dipstick as well as some pretty dark oil deposits upon wiping. Looked inside the oil fill hole upon purchase but just looked mildly varnished nothing too crazy.
Noticed a small leak from what could have been the valve cover as well but didn't scare me off as i got it for a pretty good price( These 6 speed variants are getting harder to find in good shape bodywise)
I decided to try out some short ocis with synthetic high mileage oils to try and do some cleaning. I ran techron right before i did the first oil change
- PPHM 5w20 for 4k (leak stopped within the first 1500 mi and has since still not returned)
- Maxlife HM 5w20 for 4k (Added a half quart of MMO for the last 500 miles as well as techron before i drained)
- Mobil 1 HM 5w20 1400 on the current fill as we speak
Oil usage has been relatively consistent at about a quart per 2000 miles. This wasn't that surprising as I do frequent runs up to higher rpms and some spirited driving with the car. I plan on doing one more short run for this OCI to 5k and maybe trying out an amsoil flush before changing oil again.
Would 5W30 make sense at this point or should i stay in grade? and what oil would you recommend for me? Im hoping to curb the consumption a little more if possible.
